近水平工作面通风方式的模糊决策

At present,the selection of the ventilation mode at mining face generally lack of quantitative analysis. Targeting at present situation of it, this paper put forward using the analytical hierarchy process in Fuzzy Mathematics, to establish a multi-level and multivarite Fuzzy Mathematics model, which used to select the ventilation mode of nearly horizontal mining face. The author use it to obtain weight coefficient of upward anddownward ventilation, and make fuzzy decision-making for some practical problems. The results showed that using the analytical hierarchy process can clearly describe the weight occupied by each influence factor of each decision scheme. And with it can provide relatively accurate reference data for long-term management of mining face. Which is able to ensure the safety production of underground mining face, and select ventilation mode at mining face scientifically and rationally.
