为解决中原某煤矿大矿压情况下,带式输送机机头底板不稳定和边掘边延伸输送带时影响采掘时间的问题,笔者将原计划的1部钢丝绳芯带式输送机设计成2部大槽角织物整芯阻燃带式输送机,不仅解决了上述难题,还节省了资金,且未增加人员。1矿井现状中原某煤矿已开采43年,该矿三水平丁二采区五2(丁5.6)煤层位于上石盒子组五煤中部,下距戊8煤层为105 m,煤厚0.8～6.45 m,平均厚度为3.34 m;煤层倾角较大,一般为18°～21°;埋深545～825
In order to solve the problem of large mining pressure in a coal mine in Central Plains, instability of the belt conveyor nose plate and the influence of excavation time while extending the belt on the digging edge, the author designed a steel cord belt conveyor originally planned to be 2 Department of large slot angle fabric whole core fire-retardant belt conveyor, not only solved the above problems, but also save money and did not increase staff. 1 Status of a Mine A coal mine has been explored for 43 years in Central China. The 5-2 (Ding 5.6) coal seam in the Dingbei mining area, located at the third level of the mine, is located in the middle part of the Fifth Member of the Upper Shihezi Formation and is 105 m below the E8 coal seam with a coal thickness of 0.8-6.45 m , The average thickness of 3.34 m; coal seam angle is larger, usually 18 ° ~ 21 °; depth of 545 ~ 825
