| 摘 要： | 以某矿1221(3)综放工作面为条件,根据相似理论,对综放采场上覆岩层变形规律、支承压力沿走向和倾向分布规律、支承压力在底板岩层中的传播规律及采场围岩巷道支架变形规律进行相似材料模拟实验,并与井下实测数据进行了对比。结果表明,相似材料模拟结果比较可靠,为综放采场围岩控制提供一定的理论依据。

| Abstract: | Based on similar simulation theory and the condition of 1221(3) full-mechanized caving mining face,distortion rules of overlying rock strata,abutment pressure distribution rules in dip and strike,spread rules of abutment pressure along floor strata and supports distortion rules in roadway and mining field are simulated and compared with actual observation data.The results show that similar simulation results are reliable and provide some theory bases for surrounding rock control in full-mechanized caving mining field. |
