唐山矿南翼生产区域,煤炭储量丰富、生产集中、机械化程度高,产量约占全矿总产量的一半。根据可采储量推算,南翼岩石大巷还将服务20多年。但由于上覆煤层的连续开采,岩石大巷压力日趋增大,致使部分地段遭受破坏,维修量显著增加。因此,对南翼岩石大巷进行矿力观测与研究,找出其规律性,对已有大巷的维护与未来大巷合理位置的选择都是非常必要的。
The production area of the south wing of Tangshan Mine has rich coal reserves, concentrated production and high degree of mechanization. The output accounts for about half of the total output of the mine. According to recoverable reserves projections, South Wing rock road will also serve more than 20 years. However, due to the continuous mining of overlying coal seam, the pressure of rocky lanes is increasing day by day, resulting in the destruction of some sections and the significant increase of maintenance. Therefore, it is very necessary to mine and study the rocky roadway in the south wing to find its regularity, and to maintain the existing roadway and the choice of the reasonable location of the future laneway.
