ZYJ-1000/135 drilling machine for dewatering and determination of coal in underground coal mine
ZYJ-1000/135 drilling machine for dewatering and determination of coal in underground coal mine
Gas drainage, detection of abandoned workings, dewatering, identification of coal discontinuities in advance of mining, determination of coal, roof, and floor characteristics
Coal Mine Gas (CMG) levels need to be reduced to below safe gas content threshold values, which have been set by strict safety regulations, before mining can go ahead. In the last decade, outburst risk has been brought under control by performing directional in-seam gas drainage prior to mine development and production.
The Max. drilling depth is 300m and the diameter is Φ65-Φ113. The Max. drilling speed is 1m per minute.
