Double-roadway combining speedy drivage waste rock exhaust system and method

Abstract

The invention discloses a double-roadway combining speedy drivage waste rock exhaust system and method, the system comprises a speedy drivage waste rock exhaust assembly line consisting of a boom-type roadheader, a belt conveyer, a waste rock transfer device, a waste rock bin and a mine car. The roadheader is arranged in a roadway I and a roadway II respectively, the roadway I is communicated with the roadway II via a middle drivage connection roadway, the roadheader is connected with the belt conveyer via a tail bracket, the waste rock that is cut down is conveyed onto the belt conveyer via a roahheader scraper chain, the waste rock transfer device is connected at a position where the belt conveyer is close to the tail in the roadway I, so as to convey the waste rock into the roadway II, the waste rock on the roadway II directly enters into the waste rock bin at the upper part of the roadway II via belt conveying, the waste rock falls into the mine car in a traveling roadway via pipeline conveying, and by means of continuous waste lock loading by the mine car, the waste rock is conveyed to the ground for unloading. The system and method adopts double-roadway simultaneous drivage, exhaust the waste rock automatically in a combined manner, have a fast waste rock exhaust speed, reduce the auxiliary operation personnel, and can effectively improve the roadway mechanization level and efficiency.

Description

technical field [0001] The invention relates to a coal mine underground roadway excavation and gangue discharge technology, in particular to a dual roadway joint rapid excavation gangue discharge system and method, which is especially suitable for the excavation construction of underground inclined roadways. Background technique [0002] At present, the mining of underground inclined roadways mostly adopts the operation line of "hydraulic drilling rig + backhoe loader + reloader + belt conveyor + mine car", and the operation of hydraulic drilling rig and backhoe loader is complicated, and the operator's daily operation proficiency The level of maintenance and maintenance personnel is high, and the mining efficiency of hydraulic drilling rigs is very low, which requires workers with high labor intensity and low level of mechanization, resulting in slow roadway excavation; the mined gangue needs to be loaded with a loader and transported to In the main roadway, it is discharge...

Problems solved by technology

[0002] At present, the mining of underground inclined roadways mostly adopts the operation line of "hydraulic drilling rig + backhoe loader + reloader + belt conveyor + mine car". The level of maintenance and maintenance personnel is high, and the mining efficiency of hydraulic drilling rigs is very low, which requires workers with high labor intensity and low level of mechanization, resulting in slow roadway excavation; the mined gangue needs to be loaded with a loader and transported to In the main roadway, it is discharged from the main roadway. The dark inclined roadway and the main roadway need to open multiple roadways, and only one roadway can be excavated at a time. The process is complicated and the safety factor is low, resulting in low work efficiency and low yield.
