本课题分析了不同井型、不同生产年限和不同生产条件下的矿井生产经营的发展趋势,阐述了矿井寿命周期理论,并在此基础上,提出了矿井进入衰老点的判断指标体系,包括开发强度、产量变动率、吨煤占用人数、成本变动率、盈亏系数等,然后逐一进行了运算和论证。同时还总结了不同井型衰老期的参数。它对衰老矿井的研究具有理论价值和重要现实意义,对焦作矿务局具有指导性和实用性。
This topic analyzes the development trend of mine production and management under different well types, different production years and different production conditions, expounds the mine life cycle theory, and on this basis, puts forward the judgment index system of mine entering the aging point, including the development Strength, output change rate, the number of tons of coal occupied, the cost of change rate, profit and loss coefficient, and then one by one the operation and feasibility studies. At the same time also summed up the parameters of different well-type aging. It is of theoretical value and important practical significance for the study of aging mines, and is of guidance and practicability for Jiaozuo Mining Bureau.
