对比分析了滚筒采煤机与刨煤机的特性，并将刨煤机开采技术运用于中等及薄煤层的开采中，提高了煤炭生产效率，实现了工作面采煤的全部自动化，具有广泛的推广和应用价值。
The technology of coal plough have been applied in the exploitation of medium-sized and thin coal seam through analysing and comparing the characteristic of cylinder mining machine and coal plough.
圆环链适用于煤矿刮板输送机、刨煤机、 滚筒采煤机及其它机械牵引链等。
Ring chain is applicable to coal mine scraper conveyor, plough, drum shearer and other mechanical traction chain, etc.
此刨煤机工作面以仅1.5米的采高总共向前推进了21.5米，这样的煤层高度对于采煤机来说也是可以开采的。
The plow face advanced a total of 21.6 meters with a cutting height of only 1.5 meters - an achievement impossible for any shearer in such seam heights.
