摘 要:以老公营子煤矿Ⅲ06-1(1)综采工作面为对象开展回采研究。当该工作面推进500 m时,受煤层分层线影响,煤层厚度由4.5 m减小至2.5 m,工作面倾斜长度由240 m缩短为137 m。结合现场情况,从开采经济性、设备回收及开采连续性等方面对等长工作面(斜长137 m)、刀把式工作面以及不等长工作面3种布置方式进行综合分析,确定将Ⅲ06-1(1)综采工作面布置成不等长工作面。对Ⅲ06-1(1)综采不等长工作面回采期间涉及的支架及溜槽拆解、上出口支护、施工劳动组织等进行分析。最终,采面实现了安全回采。研究成果为矿井其他类似不等长工作面回采提供了技术支持。The mining research was carried out on theⅢ06-1(1)fully-mechanized mining face of Laogongyingzi Coal Mine.When the working face was pushed 500 m,the thickness of the coal seam was reduced from 4.5 m to 2.5 m,and the inclined length of the working face was shortened from 240 m to 137 m due to the influence of the stratification line of the coal seam.According to the site situation,the three layout modes of working face with equal length(inclined length 137 m),knife handle working face and working face with unequal length were analyzed comprehensively from the aspects of mining economy,equipment recovery and mining continuity,and it was determined thatⅢ06-1(1)fully-mechanized mining face was arranged into working face with unequal length.The disassembly of support and chute,upper outlet support and construction labor organization duringⅢ06-1(1)fully-mechanized mining face with unequal length were analyzed.Finally,safe mining was realized at the mining face.The research results provide a strong technical support for the mining of other similar working face with unequal length.
