Directional Drilling Technology with Single Shot Camera in Xuyongheba Coalfield

In Xuyonggeba coalfield exploration,the majority of stratum inclination was 75 degrees,some even to 89 degrees,directional drilling equipment with single shot camera was applied.The paper expounded the difficulties of coalfield exploration in steep rock formation and the solving methods with the case of hole ZK69-22 construction,and introduced the successful application of directional drilling technology with single shot camera in coalfield exploration.
