立井箕斗在装、卸载时,均要撒落一部分煤。各矿均设置了专门用来清理撒煤的设备和峒室。分析撒煤的原因,大部分是属于箕斗装载时的撒煤。对河南省三个矿区,十多对矿井的调查,这些矿井均采用苏联设计的所谓“踏板式”装载设备。撒煤量平均为3.5‰左右,多的达到15‰,清理撒煤的峒室位于主井最底部,淋水大,潮湿而又寒冷,劳动条件极其恶劣,并且,清理撒煤占用劳动力较多,有的矿达到每天需20人左右。河南省新密矿务局,湖北煤矿设计院的广大工人和技术人员,自行设计,制造
Vertical shaft skip loading, unloading, they have to scatter a portion of the coal. All mines are set up specifically for the clean-up of coal and equipment of the 峒 room. Analysis of the reasons for coal mining, most of which belong to skip loading coal mining. Investigation of three mines in Henan Province and more than a dozen pairs of mines, all using the so-called “pedal” loading equipment designed by the Soviet Union. The average amount of coal is about 3.5 ‰, more than 15 ‰, clean the coal mines room is located at the bottom of the main shaft, the water is large, wet and cold, extremely harsh working conditions, and clean up the coal occupy more labor , Some mine reach 20 people every day or so. Xinmi Mining Bureau of Henan Province, Hubei Coal Mine Design Institute of the vast number of workers and technical staff to design, manufacture
