Optimizing roadway section and lifting mine benefit;
优化巷道断面 提高矿井效益
The stability of goaf-side roadways depends on not only the abutment distribution, but also the fracturing degree of the coal seam and rock strata alone the pillar width.
一侧采空巷道稳定性不仅与支承压力分布有关，而且与煤体受破坏程度有关。
Usually, 1 : 200 mine tunnel plan numbers its pictures according to clockwise range (or the opposite direction).
通常1:200巷道平面图的编号是按逆时针(或顺时针)方向排列的,而确定某区域内相邻图号的衔接是经常遇到的。
