The 4-2、5-2、5-3 is the main coal seam,The thickness of the three main coal is ab

7、out 2.98m,2.41m and 2.78m respectively. The coalfield geological condition is simple.The proved reserves of the coalfield are 775.19million tons. The recoverable reserves are 594.22 million tons. The normal flow of the mine is 327 m3 percent hour and the max flow of the mine is 510m3 percent hour. T

8、he mineral gas gushes the deal lower,for low gas mineral mine.The mine farmland is a single level in an comprehensive development to expand.The main transportation uses the adhesive tape transportation opporteunity coal.The working system “three-eight” is used in the Liangshuijing mine. It produced
