Feasibility Analysis and Practice of Using Carrying Framed Timber Instead of Proping up Framecl Timber at the Waste-edge Support in Zhaizhen Coal Mine

在对支架与围岩相互作用的力学分析的基础上 ,针对回采工作面矿压显现特征与规律 。

On the basis of mechanical analysis of interaction of timber and rockmass,in ligut of character and law of ground behaviour in coal face,this paper has analyzed and proved that the support result of carrying framed timber is better than proping up framed timber in zhaizhen coal mine by mathematical ways.
