冒顶

Combined with the project of'Technology of ground pressure control under high crustal stress and the mining plan research in Yinshan Mine', the stability of schistosity structural stope is studied.

主要研究内容和结论如下：(1)在现场调查的基础上，进行了工程地质岩组划分，查明了保护墩及采场片帮、冒顶的主要原因，得出了片理结构是影响采场稳定性主要因素的结论。

Based on the results of underground observations and model tests of simulated materials of immediate roof, it is expounded that fragmented roof belongs in cataclastic rock mass,and its caving characteristics is clarified in this paper too.

本文根据直接顶岩体冒顶现场实测和相似模拟实验结果，阐明综采面破碎顶板的碎裂岩体属性与冒顶特征，并建立碎裂岩体冒顶力学模型，深入研究冒顶本质原因和控制原理。

In the recent years, with the increasing excavation depth and the truth of double-level mining, drifts were strongly deformed and severely damaged in the second mine block in the Jinchuan mine. Some drifts couldn't be used normally even being repaired for many times. The geostatic emergence is very obvious. The crevasses in the surface have been occurred and enlarged quickly.

近年来，金川主力矿山二矿区随着采掘深度的不断加深以及双中段回采，水平矿柱与垂直矿柱已经形成，其地压显现明显，巷道工程变形破坏严重，个别严重地段经多次返修都无法正常使用，地表裂缝出现并加速扩展，采场与充填体时有冒顶发生。
