摘要
针对嘉乐泉煤矿8号煤层硬顶软底的赋存情况,分析2804综采工作面矿压观测数据,结合支架现场使用情况,对支架选型的合理性进行了理论分析;矿压观测和现场实践表明,ZY2500/14/28型掩护液压支架选型合理,能适应该矿硬顶软底的地质条件,并提出了工作面回采过程中应采取的措施。
On the occurrence conditions of No.8 coal seam with of jia LeQuan coal mine,by mine pressure observation and data analysis of 2804 working face,and combination with stent site usage,the rationality of hydraulic support selection is analyzed in theory.The mine pressure observation and field practice shows that ZY2500/14/28 type shield hydraulic support type selection is reasonable,it can adapt to the geological conditions of hard roof soft bottom,and put forward the measures should be taken in the process of mining face.
