赵庄煤矿煤层带压开采防治水技术研究
|
摘要
针对赵庄矿3#煤层水文地质条件复杂的情况,通过地质勘探,总结带压开采导水规律,确定该地段主要导水通道。阐述了相应的带压开采防治水技术措施:物探勘察、抽放水试验是防治水技术的前提和基础;根据相关规定计算需要留设隔水煤柱的合理宽度;注浆加固防止顶底板突水;为安全生产提供技术保障。
In view of the complicated hydrogeological conditions of 3# coal seam in Zhao Zhuang mine, we summarized the water conducting law of the mining under pressure and identified the main water conducting passageway through geological exploration. The corresponding measures for water prevention and control with pressure mining are described: geophysical prospecting and pumping test are the precondition and foundation for water prevention and control. According to the relevant regulations, the reasonable width of the coal pillar is calculated,grouting reinforcement prevents water inrush from the top and floor, and provides technical support for safe production.
