一、采区运输机巷的要求四川各矿采区运输机巷多铺设20、20B、17型链板运输机,每台最长130米,最短是根据地质变化而定,但要求运输机巷要直。运输机最高不能摆在巷道高邦顶板,最矮距巷道底板应有0.60米(如图1所示)。多年来的生产实践证明,对机巷挂中线掘进一次成巷是可行的。这样既可提高了掘进效率,又可节约机巷掘进和安装工程量(投资的15％左右)。
First, the mining area requirements of the transport lane Lane Sichuan mining area transport lane more laying 20,20 B, 17 chain conveyor, each up to 130 meters, the shortest is based on geological changes may be, but the transport lane to be straight. The maximum transport aircraft can not be placed in the high roadway roof, the shortest tunnel floor should be 0.60 meters (Figure 1). Years of production practice has proved that it is feasible to dig an alley into the middle lane of the machine lane. This will not only improve tunneling efficiency, but also save the machine tunneling and installation of the project (about 15% of investment).
