Outburst-prevention, dust collection and slag discharging integrated device for coal roadway drilling construction

Abstract

The invention discloses an outburst-prevention, dust collection and slag discharging integrated device for coal roadway drilling construction. The device comprises a drilling machine system, a hydraulic system, a compressed air system and a power supply system and further comprises an orifice dust collection device, a movable outburst-prevention baffle, a hydraulic automatic feeding device, a fixed connection device, a dust removal and slag discharging device, a hydraulic branch system and a compressed air branch system. A compressed air branch connector is formed in the upper portion of the rear end of the orifice dust collection device, a slag discharging pipe is arranged below the compressed air branch connector and inclined downwards, the movable outburst-prevention baffle is fixed to the orifice dust collection device, the hydraulic automatic feeding device is connected with the orifice dust collection device, the fixed connection device fixes the hydraulic automatic feeding device to a drilling machine, and the dust removal and slag discharging device is connected with the slag discharging pipe of the orifice dust collection device through a connecting flexible hose. The integrated device organically combines the outburst-prevention device, the dust collection device and the slag discharging device, the problem that existing orifice-series dust removal device equipment is disperse is effectively solved, multiple functions are achieved through one device, and the integrated device is easy to operate and low in cost.

Description

technical field [0001] The invention relates to a multifunctional collection and processing device for coal dust, gas and outburst prevention in coal mines. Background technique [0002] In outburst mines, the preparation roadway is generally arranged in the coal seam. In order to relieve the pressure and eliminate the outburst, a large number of bedding holes are constructed in the coal roadway for pre-extraction; The slag removal method of roadway drilling construction often uses wind power instead of water power, but the fatal weakness of wind slag removal is that a large amount of coal dust and gas are generated at the hole; protrude. A large amount of coal dust and high-concentration gas gushing out will reduce the oxygen content in the underground air of coal mines and affect human health; it may also cause a large number of casualties and facility destruction due to coal dust, gas combustion or explosion accidents. [0003] In view of the above situation, the develo...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a device for collecting coal dust, gas and outburst prevention functions for the drilling construction of coal roadways in mines, which can not only solve the outstanding problems caused by drilling holes in coal roadway excavation, but also effectively solve the problems caused by drilling. A large amount of gas gushes out of the hole to form a gas accumulation problem, and it can also effectively carry out centralized treatment of a large amount of dust gushing out
