摘要:

为取得更好的掘进工作面通风效果,根据高海拔金属矿山特殊环境需求,基于网络层次分析法(ANP),从安全效益、经济效益和技术效益3个方面,确立11个评价指标,建立了独头巷道掘进工作面通风效果评价指标的网络结构。然后利用超级决策软件解决复杂的计算问题,得到“长压短抽”、“长抽短压”和“长抽长压”3种掘进工作面通风方法的综合权重和各个评价指标的全局权重,从而选出最优通风方式。将该评价体系应用于云南省海拔3 400 m的某金属矿山,结果表明:“长压短抽”通风方式综合权重为46.16%,通风效果最佳;“供氧效果”为最重要评价指标,全局权重为20.08%,在选择高海拔矿山掘进工作面通风方式时应重点考虑其通风供氧效果。该评价体系所得结论符合高海拔矿山通风实际,并指出影响矿山通风效果的主要因素,对金属矿山制定最佳通风方式具有指导意义。

Abstract:

Ventilation of tunneling face is an important part of mine ventilation system,which is of great signi-ficance for guaranteeing the health and life safety of workers.However,the special plateau environment with low pressure and low oxygen has put forward higher requirements for ventilation effect.According to the special environmental requirements of high altitude metal mine and based on analytic network process,11 evaluation indexes were established from three aspects of safety benefit,economic benefit and technical benefit.There is a complex interaction between the evaluation indexes of the ventilation effect of the heading face.The correlation of the evaluation indexes was obtained through group discussion among 12 researchers in the field of mine ventilation.Thus the network structure of ventilation effect evaluation index of heading face was established and the final evaluation system was formed.ANP method involves many elements,the calculation process is complex and the calculation is large.According to the analysis of the ventilation effect evaluation index of the tunneling face of the high-altitude mine and the result of correlation relationship construction,the ANP model diagram of ventilation effect evaluation of the tunneling face was established in the super decision software.The comprehensive weight of three ventilation modes and the global weight of each evaluation index were calculated to select the best ventilation method.This evaluation system was applied to a metal mine at an altitude of 3 400 m in Yunnan.Ten people,including experts in mine ventilation engineering and on-the-job mine ventilation technicians,were invited to fill in the pairwise comparison judgment matrix questionnaire.By comparing the importance of the two evaluation indexes,the judgment matrix was established,and the super decision software was used for relevant calculation.The results show that the comprehensive weight of far-pressing-near-suction ventilation mode ventilation mode is 46.16%,and its ventilation effect is the best.The global weight of “oxygen supply effect” is 20.08%,which is the most important evaluation index.The oxygen supply effect should be taken into account when choosing the ventilation mode of mining face at high altitude.It is proved by practice that the conclusions obtained by the evaluation system are in line with the actual safety of mines,and can point out the main factors to evaluate the ventilation effect of mines.

Key words: high altitude metal mines, drifting ventilation, ventilation scheme, analytic network process(ANP), evaluation index, super decision software
