摘要
通过对黄陵二号煤矿回采工作面超前支承压力、侧向压力及超前、侧向顶板下沉实测数据的分析总结,得出采场压力分布特点,确定了采空区侧向压力分布范围,并验证了工作面超前支护强度。分析结果对生产实践具有重要的指导意义。
Based on the analysis and summary of the measured data of advanced support pressure,lateral pressure and roof subsidence in the working face of Huangling No. 2 coal mine,the pressure distribution characteristics were obtained,the lateral pressure distribution range was determined,and the advanced supporting intensity for working face was verified. The analysis result has important guiding significance to the production practice.
