Coal mine heading face boring exploration protection device

Abstract

The invention discloses a coal mine heading face boring exploration protection device comprising a substrate and self-locking universal wheels arranged on two sides of the substrate bottom; the substrate is provided with a first vacuum tank and second vacuum tanks; a work platform is arranged on top of a vertical rod; a drilling machine body is arranged on top of the work platform; a position, close to a drill bit, on one side of the work platform is provided with a cover plate; a guide tube connected with the first vacuum tank is arranged on the bottom of the cover plate, and provided with asolenoid valve; the first vacuum tank and the second vacuum tank and the second vacuum tanks are respectively connected via breather pipes; a dust filter net is arranged in middle position in the first vacuum tank. The protection device can provide good protection and shield effects, can fast absorb and gather leaking gas and dusts formed in boring into the vacuum tanks, thus reducing gas and dustleakage, recovering gas resources, and reducing dust damages.

Description

technical field [0001] The invention relates to the field of coal mines, in particular to a drilling protection device for coal mine driving face drilling. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. [0003] Before coal mining, it is necessary to conduct drilling exploration on the excavation face. During the drilling exploration process, there is no protective shielding mechanism at the position of the drilling rig, and the debris splash generated during drilling is likely to...

Problems solved by technology

[0003] Before coal mining, it is necessary to conduct drilling exploration on the excavation face. During the drilling exploration process, there is no protective shielding mechanism at the position of the drilling rig, and the debris splash generated during drilling is likely to cause damage to the equipment. When gas leakage occurs, generally Using the method of fast exhausting by fan not only wastes resources, but also causes certain harm to the staff more or less during the process of gas and dust being discharged along with the wind
