摘要: 针对掘锚机配套侧帮锚杆钻机施工巷道两帮上排锚杆孔角度较大及掘进时工作面粉尘浓度较大的问题,在掘锚机顶部平台加装机载锚杆钻机,代替人工完成巷道两帮上排锚杆孔施工,同时可以实现掘进面迎头煤层注水孔施工。通过在保德煤矿81309回撤通道掘进面的现场工业性试验表明,MJZ-400/300E型机载锚杆钻机结构尺寸小,与掘锚机配套适用性强,可实现多角度钻孔施工,降低了工人的劳动强度,改善了掘进面的生产环境。

Abstract: Xi’an Research Institute, China Coal Technology and Engineering Grop, Xi’an 710077, China) Abstract: In order to solve the problems of the large angle of the anchor rod hole on the two sides of the roadway and the high dust concentration in the working face, the airborne bolt drill is installed on the top platform of the roadheader instead of manually completing the construction of the anchor hole on the two sides of the roadway. At the same time, the construction of water injection hole in head-on coal seam in heading face can be realized. The field industrial test of the heading face of the 81309 withdrawal channel in Baode Coal Mine shows that the MJZ-400/ 300E airborne bolter has small structure size, strong applicability for matching with the roadheader, can realize multi-angle drilling construction, reduces the labor intensity of workers, and improves the production environment of the heading face.
