回采巷道的好坏对提高回采效率有重大意义。由于采深继续增加,这种意义还在提高。为使井下运输不受干扰,通风畅通无阻,就要不断保持足够的巷道断面,使回采巷道不要成为提高回采效率的障碍。
The quality of the mining roadway is of great significance to improve the efficiency of the recovery. As mining continues to increase, this significance is still rising. In order to make underground transportation undisturbed and ventilated unimpeded, it is necessary to keep enough sections of the roadway so that the mining roadway should not become an obstacle to improve the efficiency of the recovery.
