Analysis of Influencing Factors on the Safe and Efficient Mining of Ore-body under Riverbed and Goaf Areas

Abstract

Abstract: Based on a comprehensive analysis of complex hydro-geological conditions in Nanminghe Iron Mine，the scattered distribution of the mined-out area and the special spatial relationship between Nanminghe Iron Mine and Wannian Mine，a comprehensive safety evaluation on Nanminghe Mine and the downstream Wannian Mine during mining process of Nanminghe Iron Mine is made through the stability characteristics analysis of rock and the factors affecting mining safety.Then，a reasonable advice for safety mining of Nanminghe Iron Mine is proposed，thus providing a basis for the design of a safe and efficient mining scheme.

Key words: Safety mining, Riverbed, Golf area, Influencing factors
