The device comprises a drilled hole group drilling track calculating and drilling curve drawing module and a drilled hole group drilling quality evaluating and evaluating report outputting module, the drilled hole group drilling track calculating and drilling curve drawing module is used for calculating drilled hole group drilling tracks, drawing two-dimensional curve and three-dimensional curve of the drilling tracks and visually displaying distribution of drilled hole group under a coal mine, the drilled hole group drilling quality evaluating and evaluating report outputting module is used for evaluating drilling track quality, outputting evaluating data and result in a report form and outputting distribution of blind areas and dangerous sources for the convenience of technical personnel to check drilling completion circumstance, timely find potential safety hazards and deal with the potential safety hazards.

Description

technical field [0001] The invention relates to a drilling quality evaluation method and device for a drilling group, belonging to the technical field of drilling, in particular to a method and a device for evaluating the drilling quality of a drilling group in a coal mine. Background technique [0002] Drilling quality evaluation refers to the evaluation of the completion quality of drilling, that is, evaluating whether the deviation between the actual drilling trajectory and the design trajectory meets the specified requirements. The early coal mine underground drilling groups did not have suitable drilling trajectory measuring instruments when drilling, so they could only use the inclination angle, azimuth angle and reported drilling depth as the acceptance criteria for the quality of the drilling. In fact, due to Due to the complexity of geological conditions, the inhomogeneity of drilling equipment capabilities, and the inconsistency of construction personnel's operatio...
