Abstract

The invention relates to the technical field of drilling operation monitoring, in particular to a GPS / BD-based multisource integration mine drilling operation monitoring system and a monitoring method. The monitoring system comprises an operation far-end monitoring center and operation front-end monitoring terminals, wherein the operation far-end monitoring center issues drilling tasks and controlcommands; and the operation front-end monitoring terminals control corresponding downhole drills to conduct drilling operation according to the drilling tasks, monitor the drilling depth and drillingspeed, receive real-time positioning information of an operation positioning unit and determine and monitor the real-time drilling positions according to the carrier wave phase differential technology. Accordingly, the drilling positioning accuracy and the mine operation accuracy are ensured. The operation front-end monitoring terminals and ranging units are used in cooperation to monitor the drilling depth and drilling time in real time so as to guarantee that the drilling depth meets the requirement of the drilling tasks, and the drilling operation quality is monitored effectively.

Description

technical field [0001] The invention relates to the technical field of drilling operation monitoring, and relates to a GPS / BD-based multi-source fusion mine drilling operation monitoring system and monitoring method. Background technique [0002] At present, the method of drilling hole positioning in mine blasting sites is relatively old. Mostly, the drilling coordinates are given in advance by the blasting engineer, and then the drilling personnel use the RTK receiver to mark the site coordinates, and finally use the drilling machine to locate the markers. Drill holes in different positions to achieve a complete set of operations. This method of operation is inefficient and does not support round-the-clock operation. Since hundreds or even thousands of drilling operations need to be carried out before the blasting operation, the accuracy of these blast holes requires a deviation of less than 20cm, and the accuracy of the blast holes directly affects the effect of the blast...
