郝家梁煤矿风井开拓方案选择

Selection on Mine Development Plan of Mine Ventilation Shaft in Haojialiang Mine

郝家梁煤矿主副井均为斜井。为了科学合理地选择回风井开拓方案,从井巷工程量、投资费用、建设工期3个方面,对斜井形式与立井形式两种技术可行方案进行了比选。结果表明,斜井形式优于立井形式,推荐采用斜井形式。回风井实际施工采用了斜井形式,综掘机掘进,施工效果较好。

Mine Main and Auxiliary Shafts of Haojialiang Mine are all mine inclined shafts .In order to scientifically and rationally select a mine development plan of the mine air return ventilation shaft , from the three aspects of a engineering quantity of the mine shaft and roadway ,investment cost and construction period ,a comparison selection was conducted on the technical feasible plans of the mine inclined shaft form and the mine shaft form .The results showed that the mine inclined shaft form was better than the mine shaft form and the mine inclined shaft form was recommended to be applied .The mine inclined shaft form was applied to the actual construction of the mine air return ventilation shaft and a fully mechanized heading with fully mechanized roadheader was applied with good construction effect.
