浅谈澄合二矿开拓延深设计方案

介绍了澄合二矿二水平生产现状并指出其存在的问题,在充分利用井下现有各系统的基础上,详细描述了三水平推荐的开拓方案和原设计方案,并对两方案进行技术经济比较以凸显推荐方案的优势,从而达到减少矿井投产工程量、缩短建设工期、节省基建投资的目的.随着矿井面积扩大及煤巷支护技术成熟,采区划分应尽量减少反向运输.

Discussion on Designed Plan of Development and Deepening in Chenghe No.2 Coal Mine

In the article,the production status and existed problems of No.2 level for Chenghe No.2 Coal Mine were pointed out.On the basis of taking full advantage of underground systems,recommended development scheme and original design scheme were described in detail and compared in technical economy.Thus the advantages of recommended scheme were highlighted for reducing shaft and drift engineering quantities,shortening construction period and saving investment of infrastructure.Reverse transport should be decreased in partition of mining area as far as possible along with expansion of mine area and mature of supporting technology in coal roadway.
