In order to realize the long distance precise drilling and detection under the shaft and make up for the shortcomings of ordinary drilling rigs, such as low detection accuracy, short detection distance and inability to flexibly adjust the drilling trajectory, Shendong Mining Area generally uses long distance directional drilling rigs for drilling. At present, in Shendong mining area, long distance directional drilling rig has been widely used in advance detection after exploration in heading face, remote drainage of water accumulated in overlying goaf and accurate detection of some geological structures. During the construction of long distance directional drilling, in order to achieve the purpose of detection, it is necessary to scientifically determine the reasonable detection track in the horizontal and vertical directions before construction, and flexibly adjust the drilling direction according to the detection requirements; Before construction, relevant projects and facilities required for drilling rig construction shall be prepared in advance. After the exploration is completed, the criteria for judging various detection results shall be studied and determined. This paper introduces a series of techniques for long distance directional drilling rig exploration construction.
