摘要
软岩地下工程中围岩运动规律的认识是软岩控制的前提。龙口矿区是全国典型的软岩矿区 ,由于软岩的特殊性 ,采场和巷道的矿山压力与显现规律 ,与中硬岩层又有着较大的不同。软岩泄漏运动的提出 ,不仅对矿山、深基坑、隧道等工程的不稳定岩土支护具有相同或类似的支护机理 ,从科学、高效的角度 ,支护的基本原则应统一到普遍可以达成共识的支护理论上来 ,而且对采场围岩 ,特别是放顶煤的基本原理和控制上 ,有着特别的意义。
The aiknewledgement of the wall rock ation law in soft rock underground project paves the way for soft rock control.Longkou is Chian's typical soft rock mining are The pressure and expression law of its mining pits and lanes turns out to be quite different from that of medium hard rock.The theory of soft vock leaking action not only can be used for unsteady rock support and protection in mines,but also has a speciol magnificance on wall rock in mining pits,especially on the basical principle of top coal excavation and its control.
