摘要:
为研究解决复杂地质条件下多含水层底板突水问题,预防水害事故的发生,以河南地区某煤矿煤层底板L8灰岩、L2灰岩及O2灰岩主要含水层为研究对象,采用直流电法和井下坑透探测技术,研究分析工作面出水原因和解决办法。结果表明:通过直流电法等物探技术探测底板岩层富水带和岩溶发育带,确定含水岩层低阻区,指导注浆孔合理布置、有针对性地对煤层底板进行加固注浆,能够很好地解决复杂地质条件下多含水层底板突水问题。
Abstract:
To study and solve the problem of water burst in multi-aquifer floor under complicated geological conditions, the coal seam floor containing L8 limestone, L2 limestone and O2 limestone aquifers in a coal mine of Henan was chosen as the main research object. The DC electrical detection method and underground mine penetration detection technology were used to determine the cause of water bursting in mining face and to explore the solution for this problem. The results showed that the water burst issues in multi-aquifer floor under complicated geological conditions could be well solved by using the geophysical technologies, such as DC electrical detection technology, to explore water rich zone and Karst zone in floor strata, so as to determine low resistivity zone in water bearing layer, guide the rational layout of grouting holes, and pertinently perform reinforce grouting at coal seam floor.
