Description
Technical Field
The invention belongs to the technical field of mining dust removal, and particularly relates to a dry type filtering dust removal system for a mining drilling hole.
Background
The underground drilling of coal mine is the basic process of gas drainage and coal seam water injection, and is divided into wet drilling and dry drilling. When dry drilling is carried out, a rotary drill bit violently grinds a coal seam to generate a large amount of dust, the dust is emitted from an orifice of a drilled hole and is diffused to the surrounding environment, so that the concentration of the dust in the air in a roadway is greatly increased, the health of workers is harmed, the sight of the workers is shielded, normal operation of the workers is hindered, and most importantly, high-concentration dust can explode to bring potential safety hazards. Therefore, wet drilling is generally used at present, in which the drill rod used for wet drilling is a hollow drill rod, and water is passed through the hollow drill rod while drilling, so that dust generated during drilling is adsorbed by the water, thereby eliminating dust pollution caused by drilling. However, when the upward drilling is performed, a large amount of sewage flows out of the tunnel along the drill hole after water and dust in the drill hole are mixed, so that accumulated water in the tunnel is increased to hinder workers to walk and transport materials; when downlink drilling is carried out, water is accumulated in the drill hole and is difficult to discharge, and faults such as hole blocking, drill sticking and the like sometimes occur, so that the drilling efficiency is reduced; in addition, special water supply pipeline need be laid in wet-type drilling, to some water resource deficient, severe cold areas are difficult to adopt wet-type drilling, and wet-type drilling can make a large amount of water get into the coal seam, not only water resource waste, reduce the quality of producing the coal, be not applicable to the soft coal seam moreover.
