在建矿山深部矿体开采的采矿方法优化选择

Optimization Selection of Mining Methods of Deep Orebodies of Mines under Construction

阐述了某在建铁矿山的矿体赋存及开采情况，从采矿方法自身主要作业收支方面考虑，结合地表及开采现状对100～340m之间的深部矿体进行采矿方法的对比优化分析，经过分析影响各可行采矿方法作业收支的主要因素，结合采矿方法工艺进行作业收支计算，从经济效果出发确定最优采矿方法。

The orebody occurrence and mining situation of an iron mine under construction were introduced. The revenue and expenditure of main operations were taken into consideration. Different mining methods of deep ore- bodies ranging from 100m to 340m were compared and analyzed by combining the surface and mining situation. Through analyzing the main factors influencing the culating mined. the revenue and expenditure, the optimal revenue and expenditure of feasible mining methods and cal- mining methods with the best economic benefit can be deter-
