前进煤矿为原白沙煤电集团的骨干矿井,现隶属于湖南黑金时代南阳矿业公司,设计能力为20万t/a,储量丰富,主采煤层为急倾斜煤层,煤层发育、结构简单,煤质优良,因浅部煤层赋存良好,老窑小窑发育,其积水严重制约着前进煤矿的安全生产。自1983年投产以来曾多次发生淹井、淹工作面和局部透水事故,矿井损失巨大,2001年前,年产量一直徘徊在10万?12万t/a。因此,探讨和解决前进煤矿水患防
Qianjin Coal Mine is the backbone of the original Baisha Coal Mine Group, now under the Hunan Black Gold Nanyang Mining Company, with a design capacity of 200,000 t / a, abundant reserves, the main coal seam is steep seam, coal seam development, simple structure, coal Good quality, due to the presence of shallow coal seam, the old kiln kiln development, the water seriously restricts the progress of the coal mine safety in production. Since its commencement in 1983, it has repeatedly flooded wells, submerged work surfaces and partial flooding accidents. The losses of mines have been huge. Before 2001, the annual output has been hovering at 100,000-120,000 t / a. Therefore, to explore and solve the advance coal mine water prevention
