8m灰岩直覆半煤岩巷锚网支护技术研究

Study on anchor network support technology for 8 m tuff direct overlay semi-coal rock roadway

根据金谷煤业9+10号煤层顶底板情况可知,10904工作面巷道围岩属于刚性岩石、坚硬顶板,在进行巷道支护时,需注意刚性岩石的结构和组织、刚性岩石的孔隙型以及刚性岩石的弹性,针对不同地质条件分别进行支护设计,可有效地提高掘进速度,降低支护成本。

According to the top and bottom plate of No.9+10 coal seam of Jingu Coal Industry,the surrounding rock of 10904 working face roadway belongs to rigid rock and hard top plate.When supporting the roadway,attentions should be paid to the structure and organization of rigid rock,the pore type of rigid rock and the elasticity of rigid rock,and the support separately for different geological conditions,which can effectively improve the mining speed and reduce the support cost.
