摘要
在对大倾角煤层开采矿压显现及岩层移动特征分析的基础上 ,提出了大倾角煤层应用综合机械化开采技术的基本问题 ,建立了“支架 -围岩”相互作用模型 ,研究了大倾角煤层综合机械化开采支护系统稳定性控制途径及方法 ,结合四川华蓥山矿务局绿水洞煤矿的生产实际 ,给出了一个工程应用实例 .
Based on the analysis about rules of strata behavior and characteristics of rock movement, the elementary problems of full mechanized coal mining applied in greater pitching seam is put forward. Furthermore, a model of “support surrounding rock' relationship is made, and the controlling ways and techniques of support system stability in full mechanized coal mining of greater pitching seam are studied. Finally, an engineering practical example is given that the full mechanized coal mining of greater pitching seam has been used in Lushuidong colliery administrated by Huaying Mining Bureau,Sichuan Province.
