针对黄陵煤矿快速掘进效率的问题,从地质条件及灾害、作业环境、施工工序等主控因素对黄陵煤矿进行评估,提出黄陵煤矿智能化快速掘进工艺。结果表明:煤矿快速掘进受到施工工序较多的影响较大,锚杆(索)支护最为复杂,所占的成巷时间最久,超过59%以上。基于主控因素提出的黄陵煤矿632进风顺槽快速掘进支护与掘进施工工艺应用良好。632进风顺槽采用了智能导航系统,对锚杆转载机组进行适应性改造,将运锚机前部改造为4个普通钻架,横向布置,利用滑轨连接,钻架可通过滑轨滑动调整支护位置,可满足锚索滞后距离需求。通过工程实践减轻人员作业劳动强度,降低了安全风险,对快速掘进设备在地质条件复杂矿井应用具有一定指导意义。

Aiming at the issue of rapid excavation efficiency in Huangling Coal Mine, from the main controlling factors such as geological conditions and disasters, operating environment, and construction processes, etc, the evaluation of Huangling Coal Mine is conducted, and an intelligent rapid excavation technique for Huangling Coal Mine is proposed. The results show that the rapid excavation of coal mines is greatly affected by multiple construction processes, with anchor rod (cable) support being the most complex and taking up the longest roadway formation time, exceeding 59%. The proposed rapid excavation support and excavation construction technique for the 632 air intake crossheading of Huangling Coal Mine based on the main controlling factors are well applied. The 632 air intake croeeheading adopts an intelligent navigation system to adaptively transform the anchor rod reprinting machine unit. The front of the anchor transport machine is transformed into four ordinary drilling frames arranged horizontally and connected by sliding rails. The drilling frames can adjust the support position by sliding on the sliding rails, which can meet the requirement of anchor cable lag distance. Through engineering practice, the labor intensity of personnel operations is reduced, safety risks are lowered, and it has certain guiding significance for the application of rapid excavation equipment in mines with complex geological conditions.
