Analysis on the Development Status of Coal Mine Dust Disaster Prevention Technology in China

In recent years, with the increasing level of mechanization, automation, and intelligence in mine mining, dust pollution working environment coal mines has become increasingly serious. Coal prevention is an important work related to life, health, production safety miners, it also one technical problems production. With continuous revision improvement China′s Occupational Disease Prevention Control Law, mining enterprises have generally strengthened publicity, prevention, control occupational diseases among employees, been used as a means for improve strengthen health employees. Key work-based studies shown that China’s formed theoretical system technology control. future, will start from intelligent achieve high-precision sensing-transmission-assessment early warning, develop combined collector integrates functions atomization removal, miniaturization, dry wet mixing, large air suction capacity. The realizes efficient ventilation removal fine wide-area complex spaces such fully mechanized face face. At same time, breakthroughs achieved low-permeability seams, strong hydraulic permeability-enhancing technology, dust-proof robots, chemical suppression. This article introduces basic concepts, generation, distribution, hazards analyzes characteristics, applicable conditions, use effects various measures removal. Moreover, this proposes specific discusses development trend hope providing guidance reference
