摘要
综放开采顶煤冒放性决定煤矿的开采工艺,对煤矿设计有着指导性意义。通过对虎龙沟煤矿顶煤冒放性影响因素分析,从理论得出3-5号煤层适应综放开采,对大同煤田石炭二叠系煤层综放开采适应性给出宏观指导意见。
The mining technologies and coal mine design depend on the top coal caving.After analyzing factoring influencing the top coal caving in Hulonggou Coal Mine,the paper theoretically reaches the conclusion the fully mechanized coal caving is adaptable in the 3-5 coal layers and gives some adaptive guidance to the coal caving in the Carboniferous-Permian system of coal layers in Datong Mining Group.
