摘要
岩石力学强度较低的煤层上覆岩层受后期构造作用形成的裂隙是顶板裂隙水的主要赋存场所,多以静储量为主。裂隙的发育具有一定方向性、较好的等距性和较好的垂直性,但其非均质性较强,煤矿开采导水裂隙带沟通裂隙含水层,顶板涌水量会具有一定规律性变化。掌握该规律并做好防护应急措施,不仅可以提高地球物理探测解释成果的精确度,同时还有利于合理布置防治水措施。以新安煤矿3上201工作面为例,分析了矿井裂隙水涌水规律并提出了防治建议。
For the mechanics strength is low, some roof rock of coal effected by the later structure movement have a lot of cracks which is the main occurrence of groundwater which is static reserves. As a result of the fracture development has a certain direction, better isometric and good vertical, but with a high heterogeneity, roof drain water has certain regularity when the broken zone caused by mining reached to the reserves. It is propitious to improve the interpretation of geophysics and guidelines to the water prevention work. Analyzed the mine fissure water water law and puts forward some prevention advice in case of Xin′an coal mine, 3-upcoal, 201 working face.
