四川省石膏资源十分丰富,已探明储量约占全国探明储量的2.5%,名列全国第十位。现已知矿点有91处,生产矿山有40多个,露天和地下开采方式兼有。地下矿山有竖井、斜井、平峒三种开拓方式,主要采用房柱采矿法开采;露天矿采用直进式路堑汽车运输的开拓方式,主要采用台阶式开采。目前,四川省石膏矿山开采技术比较落后,国营矿山多用气腿式风动凿岩机或电钻凿岩,而大部分乡镇企业矿山还未摆脱手工(大锤、钢钎)打眼。各矿仍用黄色硝铵炸药、火雷管爆破崩矿;装运工作还未摆脱繁重的体力劳动,生产效率低。
Gypsum resources in Sichuan Province is very rich, has proven reserves of about 2.5% of the national proven reserves, ranked tenth in the country. It is known that there are 91 ore mines, more than 40 mines and both open-air and underground mines. There are three types of underground mines: shaft, inclined shaft and flat miner. They are mainly mined by the pillar and pillar mining method. The open pit mines use the straight-line cutting car transportation, which mainly adopts step mining. At present, the gypsum mining technology in Sichuan Province is relatively backward. Most state-owned mines use air-legged pneumatic rock drills or jackhammers, while most township and village enterprises have not yet got rid of their hand-made sledgehammers and drill rods. The mine is still using yellow ammonium nitrate explosives, fire detonators burst collapse mine; shipping work has not got rid of heavy manual labor, low production efficiency.
