Abstract: The method of artificial “try to approach” is widely used in the design of directional long gas drainage drilling in China coal mines. This method is of low efficiency, poor accuracy, and large workload, is not conducive to the safety, high yield and efficiency of the mine. To solve this technical problem, the directional drilling intelligent design method which compromises bedding, layer-through, and high position is established, and the matched software system based on Super Map Object.Net 6R is developed. The system has the function of automatic design and mapping of directional drilling, provides an automatic method for the technical personnel. Field application of the system in the Sihe Mine shows that the design time of the directional drilling is not more than 10 minutes, which greatly improves the design efficiency of directional drilling.
