岳城煤矿3号、9号煤层底板标高分别为+200~+420 m和+236~+391 m,对比煤层底板太原组灰岩水位标高456.7 m,水头高度均在煤层底板标高之上,属带承压开采。煤层底板承压水是制约矿井安全生产的主要水害之一,但由于受含水层富水性、隔水层完整性、断裂构造发育程度及导水性等因素的影响,各矿区甚至各矿井突水危险性与危害程度都存在显著的差异性。岳城矿由于受太原组灰岩极弱含水性、断裂构造发育程度低、岩层完整性好等综合因素影响,承压开采突水危险性小,即便局部发生突水,水量小易于控制,对矿井安全构不成危害。
The floor heights of No. 3 and No. 9 coal seam of Yuecheng Mine are + 200 ~ + 420 m and + 236 ~ + 391 m, respectively. The water level of limestone in Taiyuan Formation is 456.7 m above sea level, With pressure mining. However, due to the influence of water-rich aquifer, integrity of impermeable layer, degree of fracture tectonic development and water conductivity and other factors, the risk of water inrush in all mines and even mines There are significant differences in sexual and harmful levels. Due to the combination of the extremely weak water-bearing limestone in the Taiyuan Formation, the low degree of fault structure development and the integrity of rock formations, Yuecheng Mine is less prone to water inrush under confined mining, Mine safety pose harmless.
