【摘要】：我国薄煤层资源储量丰富,然而薄煤层的年产量却仅占全国总产量的10%左右,并且开采工艺落后,产出率较低,经济效益较差。研究薄煤层机械化和自动化开采技术,对提高我国薄煤层资源的回收率、延长矿井服务年限有着重要意义。本文以神东公司榆家梁煤矿为研究对象,针对榆家梁煤矿431盘区首采工作面煤层地质赋存条件以及存在的实际问题,重点阐述了国内外薄煤层开采的现状及先进技术理论、装备,通过对薄煤层综采工艺地质评价与经济效益分析,为薄煤层开采方式和设备配套提供理论依据;利用系统分析方法、采矿理论、岩层控制等理论,确定了薄煤层工作面开采工艺及设备配套、回采巷道合理布置的方式和尺寸;综合考虑各种影响因素,通过数值模拟,确定残留煤柱下方工作面回采巷道布置及合理支护方式;根据理论计算及工作面的实际情况,提出了431盘区煤层薄煤层开采自动化工作面实施方案;在此基础上,提出来薄煤层高效开采的安全技术管理措施。本研究对类似条件下的薄煤层开采技术管理有指导意义。
[Abstract]:China is rich in thin coal seam resources, but the annual output of thin coal seam accounts for only about 10% of the total output of the whole country, and the mining technology is backward, the output rate is low, and the economic benefit is poor. The mechanization and automatic mining technology of thin coal seam are studied. It is of great significance to improve the recovery rate of thin coal seam resources and prolong mine service life in China. This paper takes Yujialiang Coal Mine of Shendong Company as the research object. In view of the geological conditions and practical problems existing in the first mining face of Yujialiang Coal Mine 431, the present situation, advanced technology theory and equipment of thin coal seam mining at home and abroad are expounded emphatically. Through the geological evaluation and economic benefit analysis of fully mechanized coal mining technology in thin coal seam, it provides the theoretical basis for the matching of mining mode and equipment in thin coal seam, and makes use of the theory of system analysis, mining theory, rock stratum control, etc. The mining technology and equipment of thin coal face are determined, and the reasonable layout and size of mining roadway are determined, considering all kinds of influencing factors synthetically, through numerical simulation, the layout and reasonable supporting mode of mining roadway under residual coal pillar are determined. According to the theoretical calculation and the actual situation of the working face, this paper puts forward the implementation scheme of the automatic mining face of 431 coal seam thin coal seam in the area of 431, on the basis of which, The safe technical management measures for high efficiency mining of thin coal seam are put forward. This study is of guiding significance to the technical management of thin coal seam mining under similar conditions.
