The Hasnon Company, founded in 1837, was a French bituminous coal exploration enterprise. Despite its efforts, it conducted numerous surveys and opened three pits in Hasnon and Wallers in 1839 and 1840, within the Nord-Pas-de-Calais mining basin. Additionally, the company held a 25% stake in the from 1841 to 1843. In February 1843, the third exploratory shaft was abandoned. The company conducted two final surveys after 1843 and the onset of 1844; however, these results proved inconclusive, and operations were terminated in 1845, coinciding with the dissolution of the Hasnon Company. The concession remained unexploited and was subsequently acquired by the Anzin Mining Company, which had previously purchased Hasnon's shares in the Vicoigne Company in 1843. Anzin left the concession dormant until around 1875 when it attempted to open a pit. Subsequent exploration of the Hasnon concession has not been undertaken.
Historical context
The 1830s and 1840s were marked by a significant surge in the establishment of industrial enterprises, particularly in the mining sector. Within the Nord region, this proliferation of activity followed the discovery of substantial reserves of bituminous coal by the recently formed . A share in the company, initially sold for a mere 2,230 francs in February 1833, escalated to an astonishing 300,000 francs by January 1834. This surge in demand for the region's coal resources led to a proliferation of concession applications, with as many as 70 applications submitted in 1837 alone. However, this economic boom was not without its challenges, as many of these newly formed companies could not withstand the competitive pressures and ultimately ceased operations.
In this euphoric climate, property owners from Douai formed a company around 1833, which conducted several surveys in Hasnon in 1834 and 1835 with the assistance of the . Some members of this group conducted a separate survey in Auby, near Douai. This survey was abandoned at a depth of 140 meters after an accident. Had the endeavor persisted, it was probable that the coal-bearing terrain and coal itself would have been reached.
The Hasnon Company, an exploitation company founded in 1837 with a capital of 1,200,000 francs, was established by two survey entrepreneurs, banker and an associate. The company opened three pits in Hasnon and Wallers, which encountered the lower part of the coal formation but unsuccessfully exploited thin coal seams. While conducting surveys, the Hasnon Company successively opened the Tertres, Prés Barrés, and Bouils pits. These pits revealed drift galleries, but their mineral content was found to be insufficient for profitable exploitation, ultimately leading to their abandonment. Concurrently, the Hasnon Company was granted a concession, known as the Hasnon concession, at the onset of 1840.
While the Hasnon Company was engaged in the pursuit of coal deposits, other companies and organizations were undertaking exploratory endeavors in the vicinity. To the west, in 1838, the initiated the development of the Marchiennes pit following the completion of several surveys since 1835. Concurrently, the conducted a series of surveys in the northwest. In the east, the Cambrai Company initiated the Boitelle pit in Raismes in 1839, while the Escaut Company opened the le Bret and Évrard pits and the Bruille Company opened the Ewbank pit in the same area. The Hasnon Company did not engage in any research activities near Vicoigne, although it did submit a concession request. These four companies subsequently merged, forming the on October 1, 1841, which obtained a concession rich in lean coal in September 1841. To the south, the Anzin Mining Company opened pits in Denain and Escaudain.After discovering coal in 1826 at the Villars pit in Denain, the Anzin Mining Company opened the Saint Mark pit in Escaudain in 1830, followed by Bayard, Jean Bart, and Mathilde in 1831, Orléans in 1832, Napoléon in 1833, Casimir in 1835, Renard in 1836 in Denain, Jennings in 1837 and Escaudain in 1838 in Escaudain, Ernestine and Joseph Périer in 1841, and Chabaud la Tour in 1842 in Denain. The Hasnon Company thus owned a quarter of the Vicoigne Company. In 1843, the Anzin Mining Company acquired the Hasnon Company, thereby obtaining a quarter share of the Vicoigne Company and gaining the right to appoint two of its eight administrators.
Following a series of unsuccessful outcomes, the company, disheartened, resolved to abandon the concession. However, after consulting Chief Engineer Blavier, it undertook two final surveys. The first, at Rouges-Carrières, yielded only traces of coal, while the second, at the Drève de Wallers, encountered a completely barren coal formation.
In early 1845, the Hasnon Company declared its concession idle and subsequently sold its shares to the Anzin Mining Company. Concurrently, surveys conducted by the Société de revealed that the concession was situated in a region of particularly poor coal-bearing terrain.
For the subsequent three decades, no further exploratory endeavors were undertaken within the designated concession area. However, around 1875, the Anzin Mining Company initiated a plan to establish an excavation site, designated as the Avaleresse de Wallers, in proximity to the southernmost boundary of the Hasnon concession. The primary objective of this initiative was not the extraction of Hasnon's inherent mineral deposits but rather the intersection of the southern extension of the Vieux-Condé and Vicoigne veins, which were situated within the Anzin concession. The procurement of land was initiated, and excavation for the shaft commenced; however, work was promptly suspended and never resumed. The pit remained at the stage of an "avaleresse," defined as an initial exploratory shaft.
At the beginning of the 21st century, all traces of the three pits opened by the Hasnon Company had been eradicated. In contrast to other pits within different concessions, which are subject to annual or biennial monitoring by the Bureau of Geological and Mining Research for variables such as fill level, water level, and gas pressure, no such monitoring took place at the aforementioned three pits. Furthermore, the shaft heads at these pits have not been marked, which is standard practice.
Pits
Tertres shaft
In May of 1838, the Tertres pit was established at the location of the Tertres survey, reaching a depth of 137.60 meters. The work on the shaft was completed on January 8, 1840. Drifts were opened at depths of 110 and 134 meters, extending a considerable distance from the shaft to the north and south. However, these efforts were hindered by the discovery of only three irregular seamsA veinlet is a vein only a few centimetres thick that cannot be mined. of anthracite coal, which proved to be unprofitable for exploitation. These seams exhibited a general orientation that was approximately east-west, accompanied by a 45° dip towards the south. The work at the Tertres pit was concluded on December 15, 1840, leading to its subsequent abandonment.
Prés Barrés shaft
The Prés Barrés shaft was excavated in 1839 in a pasture situated south of Hasnon, in proximity to the Prés Barrés road, at a distance of 500 meters southeast of the Tertres shaft. The coal formation was attained at a depth of 100 meters, and the shaft's depth reached 135 meters. Long drifts were excavated at depths of 112 and 132 meters, but only a few thin coal streaks and a seam of dirty coal were encountered, none of which appeared to be commercially viable. The geology of this pit exhibited significant differences from that of the Tertres pit, leading to uncertainty regarding their geological affiliation, whether as part of a shared coal formation or a distinct geological domain. The pit was abandoned in 1841.
Boules or Bouils shaft
The Bouils (or Boules) shaft was initiated on May 16, 1840, in Wallers, along the Drève des Boules d'Hérin (known as the Trouée d'Arenberg), in the . It was located two kilometers northwest of the future Arenberg Pit and approximately 400 meters from the southeastern corner of the concession. The shaft's depth reached 135 meters, with the coal formation encountered at 116 meters. The working level was established at 130.30 meters, and a 100-meter-long drift was driven northward. All work ceased in February 1843, and in March and April 1844, the machinery was dismantled and sent to Denain. After this, from June to July 1844, the facilities were demolished, the shaft was filled in, and the site was cleared. This marked the culmination of the third and final pit of the Hasnon Company.
Surveys
Tertres survey
The Tertres survey, initiated on December 21, 1837, commenced in a pasture situated approximately 1,600 meters southwest of the Hasnon church, at a location now recognized as Rue Édouard Vaillant. The survey ultimately attained a depth of 115.46 meters. On March 11, 1838, the presence of coal was identified at a depth of 103.90 meters, subsequent to the encounter of coal-bearing strata at 102.20 meters. After the discovery of additional layers on May 3, 1838, the survey was terminated on May 6. The Tertres pit was initiated at the survey site during the same month.
Fercotte survey
The Fercotte survey, initiated in 1838, was situated in the vicinity of the northwest boundary of the concession, at a distance of 2,700 meters from the Wandignies-Hamage church and five kilometers from the Wallers church in Hasnon. The survey successfully reached the summit of the coal-bearing strata at a depth of 115 meters, subsequently traversing the strata for a distance of fifty meters without encountering coal. assessment suggested that the drilling had reached the lowest part of the coal formation. The survey was concluded in 1839, having attained a depth of 165.35 meters.
Corbets survey
The Corbets survey was initiated in 1838 within the Hasnon concession, at the intersection of Rue des Corbets in Hasnon and the avenue leading from Hasnon to Vicoigne. The coal-bearing strata were encountered at a depth of 95 meters, and the survey was terminated at 153.90 meters. The survey identified three seams of coal with a distinct appearance of being soiled, which were encountered at depths of 124, 125, and 134 meters, respectively.
Bruyère survey
The Bruyère survey, initiated on March 27, 1838, in the vicinity of Saint-Amand-les-Eaux, southwest of the town, was conducted by the Hasnon Company. This survey led to the discovery of siliceous limestone at a depth of 85 meters, thereby delineating the northern boundary of the basin between the Bruyère and Mont des Bruyères surveys. The traversal of the strata, extending from ground level to a depth of 85.92 meters, was completed within three weeks. However, the crossing of the final 5.80 meters posed significant challenges due to the extreme hardness of the terrain, necessitating a five-month extension to the survey. The Bruyère survey was officially concluded on September 24, 1838, at a depth of 91.12 meters within siliceous limestone sandstone.
First Grand Bray survey
The initial Grand Bray survey commenced on March 10, 1839, in Hasnon, situated within the Hasnon concession, at a point 650 meters north of the Bouils pit. The survey successfully entered the coal-bearing strata at 99 meters and was terminated at 144.50 meters. At a depth of 101 meters, the coal seam was encountered, measuring 80 centimeters in thickness. Two thin seams were identified at 110 and 125 meters, respectively, measuring 23 and 10 centimeters thick. A water gush was observed at a depth of 27 meters. The Grand Bray survey was concluded on August 16, 1839.
