Coal mine gas dedusting and pressurizing integrated device and application

Abstract

The invention discloses a coal mine gas dedusting and pressurizing integrated device and application. According to the device, a walking driving component drives crawler wheels to rotate so as to drive a walking trolley to move in a mine; meanwhile, an air extracting pump pumps external air into an air inlet cylinder, and makes the air contact with a first filter screen to filter dust in the air,and the filtered air enters into a box body; gas collection equipment continuously detects the gas concentration of the air and enables the air in the box body to be exhausted from an air supply cylinder under the drive of the air extracting pump, so that the walking trolley can absorb and filter flying dust in the mine in the moving process; and meanwhile, the gas concentration of the air is detected, and therefore the number of detection equipment can be reduced, and the operation space in the mine is larger.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to a coal mine gas dedusting and boosting integrated device and its application. Background technique [0002] At present, the comprehensive prevention and control of underground gas and dust plays a very important role in the safe production of coal mines. Gas drainage and dust suppression are effective means of comprehensive prevention and control. During the mining process of coal mining face, gas and dust are easy to accumulate at the corners of the coal mining face, which brings safety hazards to safe production. [0003] The existing gas drainage and dust removal are fixed installation of equipment inside the mine, and the equipment is used for gas drainage and dust collection respectively. Due to the long internal distance of the mine, it is necessary to install a large number of collection equipment and dust removal in the mine tunnel. equipment, which in turn occu...
