摘要

为解决基于悬臂式掘进机与单体钻机配合的巷道快速掘进问题,介绍了基于悬臂式掘进机的掘支锚连续平行作业工艺,形成了掘进、支护、锚固连续平行作业的施工技术体系。采用现场试验的方法,对巷道掘进与锚固分离时,顶板离层和围岩锚固性能进行了测试研究。结果表明:在顶板预先施工4根锚杆,然后在临时支架后方补打其余锚杆锚索,不会出现明显离层;不同空顶距下锚杆锚索锚固性能可以满足掘进与锚固分离要求;确定采用临时支架可以满足掘支分离生产需求。开发了连续自移式快速掘进支护装置和掘支锚连续平行作业工艺,主要包括钻探、掘进割煤、临时支护、掘进工作面锚杆打设、后方锚杆锚索打设、转载运煤、除尘等工序。在潞安漳村煤矿西下山回风巷进行了现场试验,采用新型掘支锚连续平行作业后,月进尺达到745 m,支护效果良好,掘进效率提高65%以上。
In order to solve the rapid heading problems based on a boom type roadheader with individual rock drills,based on the boom type roadheader,the paper introduced excavation,support and bolting continuous parallel operation technique to form a construction technical system with a excavation,support and bolting continuous parallel operation.The site test method was applied to measuring and test study on roof bed separation and surrounding rock anchoring performances when heading and anchoring of mine roadway were separated.The results showed that when a pre-construction of four bolts made in roof,then additional bolts and anchors were put beyond temporary supports and there was no obvious roof bed separation occurred.Under the different free roof distance,the anchoring performances of bolt and anchor could meet separation requirements of excavation and anchoring.The temporary supports determined could meet requirements of excavation and support separation operation.A continuous self moving type rapid heading and support device and a excavation,support and bolting continuous parallel operation technique were developed and were mainly including drilling exploration,excavation and coal cutting,temporary support,bolting operation of the heading face,the bolt and anchor setting beyond heading face,coal stage loading,dust control and other procedures.A site test was conducted in dip air returning gateway of underground mine at Lu'an Zhangcun Mine.After the new excavation,support and bolting continuous parallel operation applied,a month rate was 745 m,the support effect was excellent and heading efficiency was improved over 65%.
