摘要
巷道淋水现象会弱化围岩强度和锚固结构,破坏围岩的承载结构对锚杆结构产生锈蚀作用,因而增加了煤炭开采工作的危险性。山西焦煤西山煤电集团官地矿南六采区13601工作面副巷属于厚层泥岩淋水顶板煤巷,淋水现象对巷道的掘进工作造成一定的困扰,因此对其支护的设计和施工方式进行了研究和加强,并对锚杆长度和直径、排距和行距进行了计算校核计算结果显示支护参数符合要求,可见这种结构形式的支护可取得良好的支护效果。
The dripping phenomenon of roadway will weaken the strength of surrounding rock and anchor structure, and destroy the bearing structure of surrounding rock to corrode the anchor structure, thus increasing the risk of coal mining. The area 13601 face side roadway belongs to thick mudstone dripping roof coal roadway, the phenomenon of dripping water has caused certain trouble to the tunnel excavation work, Therefore, the design and construction methods of the support are studied and strengthened, and the length and diameter of bolt, row spacing and row spacing are calculated and checked. The results show that the supporting parameters meet the requirements. It can be seen that this structural form of support can achieve good support.
