| 中文摘要: |
| 安徽省淮北市青东煤矿是华东腹地最重要的矿集区之一, 其煤种具有良好的结焦性能。通过现场勘查、地表填图和物探测量等工作手段, 以及运用Surfer、AutoCAD等软件作图分析, 赋值叠加计算并制作煤层真厚度的等值线图、坚硬岩层钻孔分布图和需开展冲击倾向性鉴定区域图。青东矿8-2煤层埋深超过400 m的煤层约占总体的80%, 单层厚度超过10 m的坚硬岩层主要分布在矿井的西南、东北和中部偏南方向;西十采区的南部、西八采区的中部以及8725工作面整体和Ⅱ872工作面东部等地需要做冲击倾向性鉴定。冲击倾向性鉴定条件的分析, 为青东矿的安全开采提供理论支持和有力保障。 |
| 英文摘要: |
| Qingdong coal mine is one of the most important concentration areas in the hinterland of East China, and its coal has good coking performance. By means of field survey, surface mapping, geophysical and geochemical survey, drawing and analysis with surfer, AutoCAD and other software, the contour map of true thickness of coal seam, distribution map of borehole in hard rock stratum and area map of impact tendency identification need to be made by assignment and superposition calculation. The 8-2 seam of Qingdong coal mine has a buried depth of more than 400 m, accounting for about 80% of the total. The single layer of hard rock with a thickness of more than 10m is mainly distributed in the southwest, northeast and south of the middle of the mine. The south of the West ten mining area, the middle of the West eight mining area, the whole 8725 working face and the east of the Ⅱ 872 working face need to be identified for impact tendency. The analysis of the evaluation conditions of impact tendency provides theoretical support and strong guarantee for the safe mining of Qingdong mine. |
