The invention relates to a device for sinking drifts or etc., in underground workings, which has breasting machine, equipped with a chassis and required the demolition of the machine is an endless conveyor, which from the unloading position of the bucket passes along the machine to the opposite end.It is known that when conduct drifts in underground mines use the so-called uglerodnye machine with crawler chassis, on which the boom is to rotate and tilt the loading bucket, equipped with shock working tools. For crushing rocks, soil buckets are placed vertically down to percussion instruments, located in the lower portion could be inserted into the ground and crushing it. However, this mode of operation is relatively expensive, as it deals with only a small area. This disadvantage is eliminated by the fact that loading buckets, equipped with shock working tools are mounted on the ground with a slight slope down to remove her layers. However, this way, relatively large pieces that cannot be loaded on the conveyor system, the existing underground workings, and transported to the surface. So after blasting on these great pieces have vertically to set the buckets with shock working tools and smash them to transportable size. Therefore, this method is also relatively torontostar.com, which provides not only the breaking of a relatively elastic pieces from soil drift, but their fragmentation during further transportation.To do this on the undercarriage after breasting machine crushing machine is having on the undercarriage at least one crushing unit with the admissions funnel and an endless conveyor, so that the opposite loading the bucket end of the pneumatic conveyor of the machine combined with the admissions funnel crushing aggregate crushing machine. By connecting to a chipping machine and grinding machines provide a continuous working process of the deepening of the drift, as the detachable fender washer large pieces of rocks soil loaded on the crushing machine, where they are crushed to a transportable size, and then transferred to a conveyor installation of the roadway and thus can be transported to the surface.As the crushing units use multiple percussion instruments and/or the crusher, so repulsed blocks in a continuous process is subdivided into pieces of desired length edges and ensures the smooth transportation to the surface.Loading the bucket with his Noah offloaded to the pneumatic conveyor of the machine through the top.
