采用小直径树脂金属锚杆支护半煤岩巷道于1994年8月在打通二煤矿试验成功,并于1996年7月通过重庆市煤炭管理局组织的专家鉴定。实践证明,在半煤岩巷应用锚、网支护时,巷道选择合理的岩层层位、采用矩(梯)形断面、加以有效的临时支护,是保证锚、网支护施工安全及质量的关键之一。半煤岩巷道采用锚、网支护不仅具有较好的支护效果,而且在提高掘进单进和机械化程度、降低巷道支护成本方面都能取得明显的效果。
The use of small diameter resin and metal bolt support semi-coal rock roadway in August 1994 in the second coal mine successfully tested, and in July 1996 by the Chongqing Coal Authority organized experts identified. Practice has proved that in the semi-coal rock roadway application of anchor, net support, the roadway to choose a reasonable rock formation, the use of (ladder) -shaped cross-section, to be effective temporary support is to ensure the safety of anchor and net support construction and quality One of the keys. Semi-coal rock roadway using anchor, net support not only has a good supporting effect, but also in improving single entry and mechanization level, reduce the cost of roadway support can achieve significant results.
