庞庄矿原生产水平为-170m,为扩大生产能力,该矿进行改扩建。新生产水平为-378.5m,在井田范围内开凿新风井和新副井(落底水平为-378.5m),原老副井改造为新主井,新增箕斗硐室和煤仓,以增加一套煤炭提升设备。新水平煤炭由联系两水平的千米主皮带(16°)输送至煤仓通过箕斗从新主井提出。将老副井改造为新主井,需增加箕斗装载硐室和煤仓,这是改扩建工程中的关键。
Pangzhuang original production level of -170m, to expand production capacity, the mine expansion and expansion. The new production level is -378.5m, drilling fresh air shaft and new auxiliary shaft (the bottoming level is -378.5m) within the mine field. The old old auxiliary shaft is transformed into a new main shaft, and new skip chambers and bunkers are added to Add a set of coal lifting equipment. The new level of coal is delivered to the coal bunker from the new main shaft through the skip by a kilometer main belt (16 °) connected to both levels. To transform the old auxiliary shaft into a new main shaft, additional skip loading chambers and bunkers should be added, which is the key to the reconstruction and expansion project.
