摘要
针对赵庄煤矿3305工作面大采高综采的具体情况,分析了采场的覆岩空间结构特征及与煤壁的相互作用,研究了工作面煤壁片帮的力学机制;利用离散元数值分析软件,模拟了采高、支护强度和推进方向对煤壁稳定性的影响;通过现场的实测表明:3305工作面所选用的ZY12000/28/62D支架及布置参数能够满足正常生产的要求。
Based on the specific situation of Zhaozhuang Mine 3305＇ s large mining height face, the author analyzed stope spatial structure of overlying strata and coal-wall interaction studies Rib coal face mechanical mechanism; using discrete nu- merical analysis sottware to simulate the cutting height, supporting strength and advancing direction coal wall stability; mea- sured through the field showed that： 3305 face chosen ZY12000/28/62D stents and layout parameters to meet the normal pro- duction reauirements.
