铁煤集团大兴煤矿南五采区四层运输中巷,地质结构复杂,巷道沿煤层走向布置,标高-480m水平,走向长800m,宽2.0m,高3.5m,采用U形钢支护。整个巷道共有4个弯道,弯道角度最大为90°,最小为15°,左弯道1个,右弯道3个;30%的局部底板有起伏现象,巷道坡度4°～5°。原采用小绞车接力运输方式,设备和人员投入较多,中间转运程序复杂,维护费用高,工作效率低。为确保运输系统的安全高效,该矿设计了无极绳连续牵引绞车运输系统。
Tiezhai Daxing Coal Mine in the South five mining area four transport lane, the geological structure is complex, the roadway along the seam layout, elevation -480m level, to the long 800m, width 2.0m, height 3.5m, U-shaped steel support. There are 4 corners in the entire roadway, with a maximum angle of 90 °, a minimum of 15 °, a left corner and a right corner of 3; 30% of the local bottom has undulation and the slope of the roadway ranges from 4 ° to 5 °. The original small winch relay mode of transport, equipment and personnel into more intermediate transit procedures complex, high maintenance costs, low efficiency. In order to ensure the safe and efficient transportation system, the mine designed a continuous rope winch transport system.
