摘要
Abstract
Aiming at the steeply sloping broken thin orebody in the Mianhuakeng mine,the continuous mining method of deep hole blasting without inter-pillar was proposed.According to the technological characteristics of the method,the"inverted step shape"+up and down hole layout continuous min-ing,"positive step shape"+upward hole layout continuous mining and"positive step shape"+top pillar+upward hole layout continuous mining were proposed.The GRA-AHP and cloud model were combined to evaluate and optimize the three mining schemes,and it was concluded that the scheme of"positive step shape"+top pillar+upward hole layout is relatively safe and efficient,which pro-vides a feasible technical scheme for the mining of broken orebody in Mianhuakeng mine.关键词
