王家岭煤矿不等长综放工作面开采技术研究

Research on Mining Technology for Fully Mechanized Mining Face of Different Lengths in Wangjialing Mine

煤矿在开采过程中受矿井地质条件限制,其综采工作面多采用不等长布置方式,以最大限度地提高资源采出率。本文以王家岭煤矿18103工作面为研究对象,对其采用不等长综放工作面开采技术进行实践应用研究,取得了比较好的经济效益,为同类型地质条件的开采技术提供了参考。

In the process of mining,the coal mine is restricted by the geological conditions of the mine,and the working face of fully mechanized coal mining is adopted in different ways,so as to maximize the recovery rate of resources.Based on mine 18103 working face as the research object,the long range fully-mechanized caving mining technology which has obtained the good economic efficiency,is studied in the practical application.The research has provided good reference for mining in the similar geological conditions.
