衰老矿井确定合理开采深度的研究

STUDY ON DETERMINATION OF RATIONAL MINING DEPTH IN OLD MINES

合理开采深度的确定是矿山经营参数优化中的一个重要参数．合理确定衰老矿井的开采深度不仅关系到矿井的生产规模、服务年限，还关系到矿井今后的转产与多种经营．作者结合开滦矿务局某衰老矿井的实例，用投入产出分析法研究了开采深度问题，定量得出了该矿合理的开采深度，为上级领导制定矿井近期生产与长远规划提供较可靠的理论依据．

The determination of mine rational mining depth is an important parameter in optimization of mine management parameter.It is not only affects production scale and service period, but also affects change the line of production and diversified business. Taking Kailuan old mine as an example, rational mining depth by input output method is studied,its rational mining depth is quantitatively obtained,thus provide the reliable theoretical basis for a leading body at a higher level to drawing up a short term production and long term plan.
