Development and application of examination system for gas drainage hole along coal seam

Aiming at the problems of low efficiency and poor accuracy in the examination of bedding hole arrangement under complicated geological conditions, a set of bedding pumping drilling inspection system is designed and developed. The system can simulate the real state of coal seam occurrence according to the engineering plan, and intelligently evaluate the rationality of the layout of the extraction hole, thus consolidate the weak link in the evaluation system of the extraction standard. The application results of the construction of 1511 mining face show that the system can accurately locate the extraction blank belt and put forward a reasonable hole filling scheme, which significantly improves the gas pre-extraction effect of working face, and provides intelligent support for standardized and programmed gas treatment.
