锚杆锚索支护技术在南山煤矿的应用和发展

Application and development of bolt-net cable-rope support in our coal mine

随着开采深度的逐渐加大,岩层地质条件日趋复杂,给支护带来困难。近年,南山煤矿依靠科技进步,在破碎围岩及煤巷、半煤岩巷道施工中,大力开展以锚杆为核心的锚网、锚索、锚网索等不同形式的组合支护形式,经过不断地实践探索,取得了很好的效果。

With the increase of mining depth, gradually increasing complexity of geological conditions of rock bolting for difficult. In recent years, Nan Shah coal mine rely on scientific and technological progress, the coal roadway surrounding rock, and the construction of coal rock, vigorously develop the anchor bolt as the core in nets, and anchor cable, such different t^orms of combination support form, constantly practice, achieved good effect.
