低综采工作面大拐点中调斜开采的应用

On the Application of Adjust-slope Mining Technology in Large Inflection Point of Low Fully Mechanized Face

低综采工作面应用大拐点调斜开采技术能有效提升原煤产量和稳定性及采面布置的灵活性,具有较高的经济效益。甲煤矿11-209工作面属于低综采工作面,比较适用虚中心协调开采。本文首先介绍了甲煤矿11-209工作面的概况,经分析该工作面最适合采用调斜开采的方式,并着重分析了调斜开采的技术措施。

the application of adjust-slope mining technology in large inflection point of low fully mechanized face can effectively increased coal yield and stability and flexibility of the mining face arrangement and has high economic benefit. 11-209 working face in A coal mine belongs to low fully mechanized face, and virtual center adjust-slope mining is more applicable. This paper firstly described the present situation of a 11-209 working face in A coal mine, and this working face is most suitable for adjust- slope mining through the analysis, and emphatically analyzed the technical measures of adjust-slope mining.
