金达煤业二采区巷道布置设计方案比选

Roadway arrangement scheme selection of No.2 mining district in Jinda Coal Mining Company

针对金达煤业二采区10号、11号煤层埋藏情况,结合矿井现有的开拓系统及采区巷道情况,分析了二采区巷道布置的主要影响因素,在此基础上依据采区巷道布置原则,设计了2种二采区巷道布置方案。经技术及经济比选最终决定:刷扩原南翼运输巷和南翼回风巷,由副井井底车场新掘二采区轨道大巷,并向南平行布置二采区南翼运输大巷、二采区南翼轨道大巷和二采区南翼回风大巷至井田南部边界;刷扩原二采区辅助运输下山和辅助回风下山,并在二采区东翼轨道大巷北侧平行布置二采区东翼运输大巷至井田东部边界。

According to the occurrence No. 10 and No. 11 coal seam of No. 2 mining district in Jinda Coal Mining Company,combining with the current development system and mining roadway, the paper analyzed the main factors affecting the roadway layout. Considering the factors and roadway layout principle,two roadways arrangement scheme were designed compared in technology and economy. The final scheme was determined as follows： expanding the original transportation roadway and return airway in the south wing,excavating a new main track roadway from auxiliary shaft bottom,and arranging a parallel main transportation roadway to the south,which extend to south border of the mining field; expanding the auxiliary transportation dip and air return dip to the field, and arranging an east wing main transportation roadway at the north and parallel to the east wing main track roadway extending to the eastern border.
