摘要
保安煤矿3#煤层水文地质构造复杂,通过前期物探技术,对煤层的陷落柱进行探测分析,介绍了针对性的带压开采的防治水措施。通过对断层、陷落柱等特殊地质结构部位进行注浆加固,特别严重区域留设防水煤柱,从而达到防止突水事故发生的目的,为安全生产提供保障。
Hydrogeological structure of 3#coal seam in Baoan Coal Mine is complex.Through the early geophysical prospecting technology,the coal seam collapse column is detected and analyzed,and the targeted water prevention measures of mining under pressure are introduced.Through grouting reinforcement of fault,collapse column and other special geological structure parts,waterproof coal pillar is reserved in particularly severe areas,so as to achieve the purpose of preventing water inrush accident,and provide a guarantee for safe production.
