任楼煤矿地应力场分布特征及其对巷道变形的影响
|
摘要
随开采深度向深部发展,任楼煤矿巷道变形严重,稳定性问题逐渐成为制约生产和安全的重要问题之一。文章采用空心包体应力解除法,对任楼煤矿进行了地应力测量。实测结果表明,任楼煤矿地应力以水平应力为主导,且水平应力大于铅直应力,并随深度的增加而增大;每个测点的应力状态与其所处的构造部位、岩体结构及岩性分布等有关。研究成果对矿井深部巷道支护及矿井灾害防治有重要的指导意义。
In Renlou Coal Mine,as the mining is going deeper and deeper,the deformation of the tunnel becomes more serious.And the tunnel stability becomes one of the most important issues that concern the safety and production.In this paper,the rock stress in the mine was measured with the stress relieving method,and the result shows that the horizontal stress is predominant.At the same time,the horizontal stress is proved to be higher than the vertical one,and the stress becomes greater as the depth increases.The stress situation at each positon is related to many factors,such as the structure position,rock structure,lithologic structure and so on.The obtained results are valuable for the roadway support and mine disaster prevention in deep coal mines.
