摘要
为了改善留巷的应力状态,降低巷道维护难度,保证矿井安全生产,以煤矿实际巷道工程概况为基础,分析了水力压裂切顶卸压前后的应力分布,研究了试验机具与设备,设计了压裂参数及水力压裂切顶技术施工工艺,并分析了水力压裂切顶技的安全技术措施。研究为类似矿井地质条件的巷道切顶卸压提供了借鉴。
In order to improve the stress state of roadway retention,reduce the difficulty of roadway maintenance,and ensure safe production in the mine,based on the actual roadway engineering overview of the coal mine,the stress distribution before and after the hydraulic fracturing top cut and pressure relief was analyzed,and the test equipment and equipment were designed.Fracturing parameters and hydraulic fracturing roof cutting technology construction technology,and analysis of hydraulic fracturing roof cutting technology safety technical measures.The research provided a reference for roof cutting and decompression in similar mine geological conditions.
