摘要
以隆安煤业11#下组煤层为研究对象,对其煤层条件、围岩地质条件、围岩结构和强度等地质力学性质进行了分析,对11301工作面巷道现有支护进行了描述和分析,从支护材料、支护方式、组合构件、预紧力等方面提出了11305工作面巷道的支护方案,对11#下组煤层进行了支护优化。
The 11#lower coal seam in Long’an mine were studied as the research objects.The geomechanical properties such as coal seam conditions,surrounding rock geological conditions,surrounding rock structure and surrounding are analyzed.The description and analysis of existing support in 11301 working face roadway is provided.The supporting scheme of 11305 working face roadway was put forward from the aspects of supporting materials,supporting methods,composite components,pre-tightening force,etc.The support optimization for 11#lower coal seam was crried out.
