15~#煤综采工作面顶板弱化处理效果分析

Analysis of the Effect of Coal Roof Weakening at Fully Mechanized Working Face of 15~# Coal

以凤凰山煤矿XV1303综采工作面为例,为了确保工作面初采期间采空区顶板能够顺利垮落,杜绝顶板事故发生,探讨钻孔施工相关技术参数和水力压裂实施工序,生产过程中采用矿压设备对工作面进行矿压监测,并通过收集的数据分析回采期间顶板压力分布状况,验证液压支架的工况和水力压裂技术的应用效果。

Taking XV1303 fully mechanized working face of Fenghuangshan Coal Mine as the example, this paper discussed the related technical parameters of drilling construction and the hydraulic fracturing process in order to ensure the successful roof caving in the preliminary extraction at the working face and prevent roof accidents. Pressure equipment was adopted to monitor the pressure of the working face in the process of production, roof pressure distribution was analyzed through the data collection during the extraction and the operation condition of the hydraulic support and the effect of the application of hydraulic fracturing technology were verified in this paper.
