摘要
通过对软岩的性质、变形及破坏机理的认识,以及对深部开采的应力特点分析,对现有的支护形式进行比较,从而得出在各种煤层赋存条件下使用不同的支护形式的技术和经济区别。
Through understanding the properties, deformation and destroying mechanisation of soft rocks, analyzing the stress characters of depth portion mining, comparing with the nowadays support forms, The difference of technology and economicy that use different support forms is obtained by analyzing the existing conditions of every coal seam.
