摘要/Abstract

摘要： 概述庙沟铁矿深部资源地质勘探所取得的有关Ⅱ号矿体围岩性质、产状、厚度、尖灭、矿石质量、结构、构造以及铁矿石资源量等勘探成果。从本次勘探存在问题、勘探问题解决建议2个方面，论述庙沟铁矿深部资源地质勘探后所必须思考的问题，在此基础上，对露天转地下2种开采过渡方式的经济效益进行对比分析，得出 “露天扩界开采至372 m水平转入地下”的开采过渡方式是最合理的开采过渡方式。

Abstract: The results of the geological exploration of deep resources at Miaogou Iron Mine are described, including the country rock properties, occurrence, thickness, wedging out, ore properties, structure and texture, and iron ore quantity of orebody II.The problems and solutions of this exploration and the issues needing to be considered after this exploration are discussed.Based on this, the economic benefits of the two methods of the transition from open-pit to underground mining are compared and it is concluded that the most rational plan is to transit the mining to underground at 372 m level.

Key words: Deep resource exploration, Mining transition mode, Thinking, Comparison
