某矿井深部集中生产技术改造总体部署时,利用现有井筒下延开拓矿井深部井区,主斜井井口1850～1550m水平倾角为25°,1550～1360m水平倾角为28°,设计生产能力150万t/a。1提升系统现状及存在的问题主斜井主提升系统担负着原煤的运输任务,采用2JK-2.5/20型单绳缠绕式矿井提升机,双钩6t箕斗,配JR1410-8型电动机(6kV,280kW),最大提升速度4.7m/s,最大提升长度750m,最大静张力90kN,最大静张力差55kN,使用6×7+1-28-155型
During the overall deployment of deep centralized production and technological transformation in a mine, the well depth of the well is extended to the depth of 1850 ~ 1550m under the existing wellbore, the horizontal inclination angle is 25 °, the horizontal inclination angle of 1550 ~ 1360m is 28 °, and the designed production capacity is 1.5 million t / a. 1 to enhance the system status quo and existing problems The main inclined shaft main lifting system is responsible for the transportation of raw coal tasks, using 2JK-2.5 / 20 single rope winding mine hoist, double hook 6t skip, with JR1410-8 motor (6kV, 280kW), the maximum lifting speed of 4.7m / s, the maximum lifting length of 750m, the maximum static tension of 90kN, the maximum static tension difference of 55kN, the use of 6 × 7 + 1-28-155 type
