综采工作面回采工艺研究

Study on Mining Technology of Fully Mechanized Working Face

针对当前煤炭需求量越来越大,采煤设备能力一定的情况下如何提升工作面煤炭的产量,通过对我国煤炭最高年产量的变化和综采技术现状研究的基础上,对比了对拉工作面回采及超长工作面双采煤机单向采煤机工艺的特点,为进一步提升煤矿年产量提供了指导。

In view of the increasing demand for coal and the certain capacity of coal mining equipment,how to improve the output of coal in the working face is discussed.Based on the study of the change of the maximum annual output of coal and the status quo of comprehensive mining technology in China,this paper compares the technology characteristics of double shearer and one-way shearer in the opposite and extra long working faces,which provides guidance for further improving the annual output of coal mine.
