4. Applications
1)Gas drainage directional borehole drilling in Dafosi Coal Mine, Shaanxi, China
Maximum depth of 1024m borehole was achieved in 2012. 4 branches were accomplished, 3 of them reached the targets accurately. Average daily drilling depth was as high as 160m. The fact shows that ZDY6000LD(A) directional drilling system can drill boreholes as depth as 1000m with relative high drilling efficiency.
2)Gas drainage directional borehole drilling in Rujigou Coal Mine, Ningxia, China
Deep hole directional drilling were conducted in Rujigou Coal Mine to replace shallow borehole drilling, which lead to high gas drainage efficiency, less drilling operation and lower cost (reduced more than 40% labor and material cost)
