摘要
为解决煤峪口矿井田开拓布局问题,结合工业场地位置,分析井下及地面生产系统,提出了2个开拓方案,从技术和经济两方面分析开拓方案的优缺点。选定的在东北角工业场地采用斜井开拓方案,井筒压煤减少20.8万t,初期投资节约957.9万元,实现安全且高效生产。
In order to solve the problem of field development and layout of Meiyukou Mine,combined with the location of industrial site,the underground and surface production systems are analyzed,and two development schemes are proposed.The advantages and disadvantages of the development scheme are analyzed from both technical and economic aspects.The selected industrial site in the northeast corner adopts the inclined shaft development scheme,which reduces the coal pressure in the shaft by 208000 tons,saves 9.579 million yuan in initial investment,and realizes safe and high efficiency production.
