CCTEG

1. Introduction

Specifically designed to drill especially long

directional drilling boreholes in explosive

underground environments

The rig has a compact footprint

mounted on tracks, and is integrated

with certified flameproof electrics

and flameproof laptop

The rigs is designed to drill in-seam in

excess of 1000m with downhole motor,

directional drilling management system,

CHD drill rods and PDC drill bits

Borehole trajectory (profile view)Borehole trajectory (plan view)

A single hole with 77 sidetracks was accomplished in coal seam. Maximum of depth

of the borehole is 834m. The average drill efficiency reached 247 m/d. One single

borehole can cover the whole areas which reduced gas drainage cost significantly

4. Application

Multi-sidetracks in-seam directional drilling for gas drainage
