主井箕斗卸载撒煤量大的改造与应用

Modification and application of the main shaft skip unloading with large scattering coal amount

主井箕斗卸载过程中,撒煤量大,分别落入主井底或吸入主井风硐内,造成箕斗转载效率低,主井风硐和主井清撤硐室清理工作量大;通过对卸载点进行机械改造,解决了上述问题,取得了良好的效果。

In unloading process of the main shaft skip, the scattering coal amount is large, which respectively fall intothe main shaft bottom or are attracted the wind tunnel of the main shaft, and result in low skip reproduction efficiency,the cleaning workload of the wind tunnel of the main shaft and the main shaft bottom is large; the mechanicaltransformation of unloading points, solved the above problems, and achieved good results.
