Problems solved by technology
In recent years, with the continuous improvement of coal mine mechanization, the dust problem has become more and more serious. A pair of sharp contradictions have been formed, especially the relevant departments attach great importance to the comprehensive dust prevention of mines, and the requirements for the comprehensive dust prevention level of mines are getting higher and higher. The dust problem caused by coal mines caused poor sanitary conditions and flying dust, which increased the probability of silicosis among workers and laid hidden dangers for safe production.

Description
technical field [0001] The invention relates to a coal mine underground dust removal device, in particular to an energy-saving self-circulation dust removal device for a shotcrete machine. Background technique [0002] At present, dust is still one of the main problems plaguing coal mine production. High-concentration dust poses a serious threat to coal mine safety, especially respirable dust is the direct cause of inducing pneumoconiosis among workers. Therefore, reduce dust concentration, especially reduce respirability The concentration of dust is very necessary and also the main technical problem. In recent years, with the continuous improvement of coal mine mechanization, the dust problem has become more and more serious. A pair of sharp contradictions have been formed, especially the relevant departments attach great importance to the comprehensive dust prevention of mines, and the requirements for the comprehensive dust prevention level of mines are getting higher an...
