摘要
通过对榆树田煤矿110501工作面顶煤冒放性进行研究分析,发现煤层赋存深度、煤体强度、顶煤具有高韧性性质、顶煤裂隙分布、煤层夹矸层和顶板岩层等因素对工作面顶煤冒放性有影响,从而找出榆树田煤矿110501工作面顶煤放出率低的原因,对该矿以后的生产改进方案提供了思路。
Based on the study of top coal caving and caving characteristics of 110501 working face in Yushutian Coal Mine,the factors influencing the top coal caving ability,such as coal seam occurrence depth,coal body strength,top coal with high toughness,top coal fracture distribution,coal seam gangue layer and roof rock strata,etc.,were summarized.The reasons for low top coal caving rate in 110501 working face of Yushutian Coal Mine were analyzed,and the improvement measures for the future production of the mine were also put forward.
