小纪汗煤矿13盘区大巷优化设计

Xiaojihan Coal Mine panel No.13 main roadway design improvement

为了实现降本增效目的,减少小纪汗煤矿大巷延伸投资,结合原开采设计情况并综合考虑矿井排水、供电、主辅运输、通风等因素,通过理论分析和风量验算,提出将13盘区大巷布置由5条调整为3条,大巷布置调整后能够减少矿井13盘区开拓投资,同时矿井能够达到设计产能,并且提出相应的生产接续计划。

To reduce cost and increase benefits, the original mining design was studied from drainage,power supply,transportation,ventilation and other aspects. The main roadway design of panel No. 13 was reduced to three from five. This improvement effectively reduced the expansion cost. Production plan was provided accordingly to ensure the capacity achieving design value.
