Pine River Mine To Achieve High Yield And Efficiency Feasibility Study

In view of how to construct a modernized high production and high efficiency mine in SongHe mine-field to realize one well with one face, this paper demonstrated the question from the technology and economy aspect with reforming the roadway arrangement, introducing the advanced craft equipment and improving the assistant transportation as the core of the subject. It deeply discussed the possibility of realizing high production and high efficiency by changing of the appearance regularity of mining dynamic pressure, changing of ventilation pattern as well as the transporting by trackless rubber tire, pumping methane in advance to thoroughly cure the mine of methane problem and to resolutethe question of exploitation thin layer of coal.Applying rock theory, it analyzed in detail the relation between roadwaydetortion and the normal distance of coal layer, the roadway position and the mining dynamic influence.
