风水沟煤矿因受小煤窑侵占，采场接续非常紧张，正常生产难以维持，为改变生产被动局面．该矿在确定延深方式时采用方案比较法进行了优化选择。施工后，实现了充分利用现有生产系统、工程量最小、花钱最省、投产最快的目的，确保矿井稳产、高产。 Due to the foul shoal coal mine occupied by small coal mines, stope connection is very tight, the normal production is difficult to maintain, in order to change the passive production situation. The mine in determining the way to deepen the use of program comparison method for optimal selection. After construction, the project aims to make full use of existing production systems, minimize construction cost, save the most money and put into operation at the fastest speed to ensure stable and high-yielding mines.
