1) fully-mechanized face in coal seam
煤层综采面
1.
This paper study the long hole loosen blasting technology for bottom floor rock of fully-mechanized face in coal seam based on theoretical analysis, such as Explosive Mechanics, Rock Mechanics and Damage Mechanics etc, and what s more, the commercial testing in status quo has verified it.
本文在爆炸力学、岩体力学、断裂损伤力学等多门学科理论分析的基础上,结合现场工业试验对煤层综采面底板岩石深孔松动爆破技术进行了研究。
6) fully-mechanized top-coal caving mining
综采放顶煤面
1.
Based on theoretical analysis and numerical simulation, the stability of surrounding rock of roadway driving along next goaf for fully-mechanized top-coal caving mining was studied.
用理论分析和数值计算方法研究了综采放顶煤面沿空巷道的围岩稳定性,分析了影响掘巷位置的几个因素─—老顶岩层垮落特征、直接顶和煤体变形特点及采空侧支承压力分布规律,提出了沿空巷道的合理位置。
补充资料:综采放顶煤
综采放顶煤:厚煤层煤炭开采技术之一。把原来分层开采的煤炭,一次采完。方法是,在煤层底部按传统方法开采,使上面的煤炭在矿压的作用下,自动落下来。
