随着煤矿的开拓,浅部或上山矿逐渐减少,向深部将遇到不同程度的水文地质问题,若情况不明、措施不当,则将影响正常开采,甚至给国家和人民的生命财产造成危害和损失。江川煤矿是地方国营煤矿,年产褐煤15万吨。经20多年的开采,1700米标高以上的浅部煤层即将开采完毕,下一步将开拓1700—1660米标高的煤炭资源,要遇到基底高压裂隙孔隙水的威胁,会出现底板涌水、溃沙和底鼓等现象,将严重影响生产的安全。在此情况下,江川煤矿注意做好矿山水文地质工作,为矿山安全生产和下一采矿水平提供了可靠资料。现推荐给读者,以供参考。
With the development of coal mines, the shallow or upper mines will gradually decrease, and will encounter different degrees of hydrogeological problems to the deep level. If the situation is not clear and the measures are not properly implemented, the normal exploitation will be affected and even the lives and property of the country and people will be harmed. loss. Jiangchuan Coal Mine is a local state-owned coal mine with an annual output of 150,000 tons of lignite. After more than 20 years of mining, the shallow coal seams above 1700 meters above sea level are about to be mined. The next step will be to develop 1700-1660 m elevation coal resources. In order to meet the threat of pore water under high pressure fissures in the basement, gushing water, Bottom drum and other phenomena, will seriously affect the safety of production. In this case, Jiangchuan Coal Mine pays great attention to mine hydrogeological work and provides reliable information for mine safety production and the next mining level. Now recommended to readers, for reference.
