To meet the needs of coal fall down mining technology, the technical reformation have been made on 6mg200w shearer and therefore it can use in the big seamAngle, more ore and seam broken condition.
There are series problems exist in the existing thick seam mining technology with large dip Angle, thus cause low extraction rate, poor safety and high cost.
现有的大倾角厚煤层开采技术存在着一系列问题,从而导致煤矿回采率低,安全性差,成本高。
