神东矿区特厚煤层大采高一次采全高开采工艺研究

Technique of Large-mining-height Full Height Cutting Mining in Extrathick Seams of Shendong Mining Area

以上湾煤矿12206工作面为例,从回采设计、开采工艺及技术等方面,对综采大采高一次采全高工艺进行分析研究,表明其在回采率、吨煤成本、安全管控和设备配套等方面都有较大优势。

Taking an example of No.12206 working face in Shangwan mine, in terms of mining design and technique, the large-mining-height full height cutting mining technique was studied. The results showed that the technique had advantages in recovery ratio, unit cost of coal mining, safety control, and equipment matching.
