摘 要:受煤矿资源储量及开采速度限制,山东等省大多数矿井已进入矿井开采后期,受多种因素制约,煤矿开采末期经济效益增长面临较大的局限性,如何重新激发老旧矿井活力及促使利益最大化是一个亟待解决的难题。论文着重对矿井末期经济发展主要影响因素展开分析,阐述了效益增长困境,并据此针对性提出相关对策。Due to the limitation of coal resource reserves and mining speed, most mines in Shandong and other provinces have entered the late stage of mine mining. Restricted by many factors, the growth of economic benefits at the end of coal mining is faced with great limitations. How to re-stimulate the vitality of old mines and maximize benefits is an urgent problem to be solved. This paper focuses on the analysis of the main influencing factors of the economic development at the end of the mine, expounds the predicament of benefit growth, and puts forward the relevant countermeasures accordingly.
