Abstract

The invention relates to the technical field of mine drilling monitoring, and particularly relates to a method and device for monitoring drilling depth and the drilling speed of a mine down-the-hole drill. The method comprises the steps that an initial zero point of the corresponding stroke of an initial drill rod is determined, the down-the-hole drill is controlled to sink the initial drill rod,and the maximum drilling depth of the corresponding stroke of the initial drill rod is obtained; a connection zero point of the corresponding stroke of a connection drill rod is determined, the down-the-hole drill is controlled to be connected with the drill rod, the real-time drilling depth transmitted back by a distance measuring unit is received, and the drilling depth of the connection drill rod at the current moment is updated; and whether the sum of the drilling depths of the sunk drill rods is equal to the preset depth or not is judged. According to the method and device, the zero pointof each drill rod is reasonably set, the drilling depth of each drill rod is accurately monitored in combination with the real-time drilling depth transmitted back by the distance measuring unit, andtherefore the effective stroke and the effective stroke time generated in the ascending and descending process of the down-the-hole drill are accurately obtained, the total drilling depth accuratelyreaches the preset depth, and the reliability of monitoring the drilling depth of the mine down-the-hole drill is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mine drilling monitoring, and relates to a method and device for monitoring the drilling depth and drilling speed of a mine down-the-hole drilling rig. Background technique [0002] At present, down-the-hole drilling rigs are used on a large scale in the mining area to monitor the drilling depth and drilling speed of the down-the-hole drilling rig in real time, which is important for safe and stable production in the mining area, and to judge the hardness of each rock layer in the mining area according to the drilling speed when the output power of the air compressor is constant. It is of great significance to use different ratios of emulsion explosives for different hardness rock formations, and then accumulate big data on the platform to realize the intelligent deployment of emulsion explosives. Existing methods for monitoring the drilling depth of down-the-hole drilling rigs in mines are mostly manual ...
