Evaluation Research Of Ventilation System In Changping Coal Mine

Mine ventilation is an essential part of mine production, and the reasonable and reliable mine ventilation system evaluation has an important significance to ensure the mine safety production. Based on the mine actual needs, paper conducts the comprehensive anslysis research for the national laws and regulations and on-site situation, then identifies dangerous and harmful factors and proposed conventional and unconventional evaluation system. Conventional evaluation is mainly using the method of the safety check list to conduct analysis and evaluation; unconventional evaluation is proposing some indicators to evaluate the mine ventilation system, such as the reasonable main parameters of the mine ventilation network, the rational structure of the mine ventilation network, the mine ventilation capacity, the reasonable of series ventilation, the economic and rationality for the fan, the capacity for resisting disasters through the reversal ventilation and so on. Meanwhile, it has also doing the field application and guide practice for the Changping Mine of the Jincheng Anthracite Mining Group, and through the evaluation, it has playing a positive role to ensure the mine production safely and efficiently.
