摘要
本文分析了成家庄煤矿11301工作面开采压力的特征,探讨了影响工作面开采压力的主要因素,并结合11301工作面开采条件,开展了新型水力压裂技术防治工作。结果表明,11301工作面平均压力步距从20.6 m降至16.3 m,动载系数从1.37降至1.14,工作面顶板弱化效果显著。
This paper analyzes the characteristics of mining pressure in the 11301 working face of Chengjiazhuang Coal Mine,explores the main factors that affect the mining pressure.Based on the mining conditions of the 11301 working face,a new hydraulic fracturing technology prevention and control work has been carried out.The results show that the average pressure step of the 11301 working face decreased from 20.6 m to 16.3 m,and the dynamic load coefficient decreased from 1.37 to 1.14.The weakening effect of the working face roof is significant.
