螺旋钻式采煤机钻具偏斜控制方法研究

Research on Drill Deflection Control Method of Auger Drill Miner

螺旋钻式采煤机是一种能够解决薄与极薄煤层开采、提高煤炭资源回收率的采煤设备。由于螺旋钻式采煤机还存在钻具偏斜的问题难于解决,一直制约其在薄煤层开采中的广泛推广应用。根据螺旋钻式采煤机在现场应用情况和石油钻井中井斜控制技术,对螺旋钻式采煤机钻具偏斜进行研究,并提出几种较为可行的解决方法。

Auger Drill Miner was a new machine for thin and very thin seam mining and improving the recovery rate of coal resources. The problem that the drill of Auger Drill Miner deflection is still difficult to resole, so the auger drill miner has been constrained in thin-seam mining in the widely used.This paper based on the field application of auger drill miner and the deviation control technology in oil drilling. At last, this paper puts forward several more viable solution by doing some research on drill deflection of Auger Drill Miner
