Abstract: | In order to improve the production efficiency, reduce production costs, improve economic benefit of mine, we used non-pillar sublevel caving method as the main method of the ore body mining based on the detailed analysis of orebody occurrence characteristics of yangershan iron-copper mine. This paper discusses in detail the applicability mining method, stoping process parameters and site management experience. It is proved by practice that the non-pillar sublevel caving method in yangershan iron-copper mine is technically feasible and economically reasonable. |
