水力压裂切顶卸压技术在斜沟矿18108工作面的应用

Application of Hydraulic Fracturing Top Cutting Pressure Relief Technology in 18108 Working Face of Xiegou Mine

斜沟矿为解决18108工作面坚硬顶板难垮落造成的巷道稳定性差的问题,基于水力压裂卸压机理,采用数值模拟软件对水力压裂切顶卸压对边界巷道、辅助巷道的稳定性影响进行研究,发现经过水力压裂切顶卸压后巷道的稳定性得到了大幅度的改善,较未经水力压裂切顶卸压时应力更加平稳,提升,也为矿井地质条件相类似工作的顶板治理提供了参考与借鉴。

In order to solve the problem of poor roadway stability caused by the hard roof of 18108 working face,Xiegou mine used numerical simulation software to study the influence of hydraulic fracturing top cutting and pressure relief on the stability of boundary roadway and auxiliary roadway based on the hydraulic fracturing pressure relief mechanism.It was found that the stability of roadway after hydraulic fracturing top cutting and pressure relief was greatly improved,and the stress was more stable and increased than that without hydraulic fracturing top cutting and pressure relief.It also provides a reference for roof treatment with similar geological conditions in the mine.
