水泥卷锚杆由西安矿业学院锚杆研究组在实验室研制出来的。1983年4月至11月由我公司第四工程处、科研所与该研究组合作,在三河尖矿主井-700米水平临时水仑通风巷道及风井-420米东冀集中轨道上山中分别进行工业性试验。主井-700米水平临时水仑通风巷道的试验情况如下:巷道净断面7.59平方米,掘进断面8.4平方米,全96长米,服务年限约4至6年(见图1、2)。
Cement bolt by the Xi’an Institute of Mining bolt research group developed in the laboratory. April 1983 to November by our company’s Fourth Engineering Department, research institutes and the research team work together, in the main river wells in Sanhejian -700 meters horizontal temporary water ventilation tunnel and wind shaft -420 meters Dongji concentrated orbital Industrial test separately. The test conditions of temporary well water ventilation tunnel with main shaft of -700m are as follows: The tunnel has a net section of 7.59m2 and a driving section of 8.4m2 with a total length of 96m and a service life of about 4-6 years (see Figures 1 and 2).
