浅析复杂地质破碎带顺槽巷道支护技术应用

Analysis on the Application of Roadway Support Technology in Complex Geological Fracture Zone

为了控制顶板的完整性,针对巷道掘进过程中顶板破碎冒落存在的问题,对支护工艺进行了优化,通过复合支护加杠杆式临时支护前探梁的配合,适当增加锚杆和锚索的支护强度,减少间排距。从实际应用来看,该工艺在掘进过程能实现安全、高效掘进,取得了良好效果。

In order to control the integrity of the roof,the support technology was optimized aiming at the problems existing in roof crushing and caving during roadway tunneling.Through the combination of composite support and lever type front beam appropriately increases the support strength of bolt and anchor cable,and the spacing is also reduced.From the practical application,the technology can realize safe and efficient tunneling and has achieved good results.
