我处在黄港矿井立井施工时,采用单钢丝绳悬吊胶皮风筒的方法,完成了453米井巷工程通风任务,在与风井即将贯通时的有效风量为64米’/分,能及时排除放炮后的炮烟,满足了施工要求。 该矿井为年产量21万吨低瓦斯矿井,一立(提升井)一斜(风井)开拓方式,立井与斜井的最短贯通距离为1183米,井筒、井底车场布置在煤层顶板长兴灰岩中,离煤层
I was in Huanggang mine shaft construction, the use of single wire rope hanging rubber duct method to complete the 453-meter shaft project ventilation tasks, and the wind shaft is about to pass the effective air flow of 64 m / min, can be promptly excluded After blasting the gun smoke, to meet the construction requirements. The mine is an annual output of 210,000 tons of low-gas coal mine, a stand (lift shaft) a ramp (wind shaft) to develop ways, vertical shaft and inclined shaft of the shortest through distance of 1183 meters, wellbore, bottom of the car yard layout in the coal seam roof Changxing gray Rock, from the seam
