Abstract

The invention discloses a drilling construction automatically-monitoring system. The drilling construction automatically-monitoring system comprises a drilling machine base (10), a feeder (4), a chuck (3), a clamp (2), a drill rod (1), a monitoring microcomputer (20), a signal processor (8), an inclinometer (7), a laser sensor (5) mounted on the side surface and at the rear of a drilling machine, an interruptible circuit device (14) for controlling the laser sensor, and a laser reflector board (6) which is mounted on a movable platform on the side surface of the head portion of the drilling machine and can move forth and backward along with a drill of the drilling machine. The inclinometer is mounted on the side surface of the drill rod and is parallel to the drill rod; the clamp, the chuck and the feeder are connected with the interruptible circuit device respectively through a clam hydraulic pipeline, a chuck hydraulic pipeline and a feeder hydraulic pipeline; the interruptible circuit device is connected with the laser sensor. The drilling construction automatically-monitoring system can achieve monitoring along with drilling and is high in measuring precision and good in practicality, meanwhile, managers can conveniently obtain the construction progress in real time, supervise the work and achieve timely scheduling.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an automatic monitoring system for drilling construction used for monitoring drilling conditions in mines. Background technique [0002] As we all know, drilling construction is the most basic and frequent work underground in coal mines. For example, roadway excavation and gas drainage require drilling operations on rock formations and coal seams. In the drilling construction process, the drilling depth and drilling azimuth are very important parameters. Whether the drilling can be completed in place is of great significance for eliminating potential safety hazards, pressure relief, and gas extraction. [0003] At present, the detection of borehole depth and borehole azimuth is mainly obtained by drilling rig operators or acceptance personnel by counting the number of drill pipes and measuring with an azimuth measuring instrument. This manual detection method takes a long time, has low det...

AI Technical Summary

Problems solved by technology

This manual detection method takes a long time, has low detection efficiency, and has large human errors; at the same time, it cannot realize measurement while drilling, and its real-time performance is poor.

In addition, before the drilling construction, it is necessary to formulate a detailed plan for the drilling construction layout in a certain area, in theory to eliminate potential safety hazards and avoid blind drainage areas; , it is prone to the phenomenon that the actual drilling construction is inconsistent with the drilling construction design plan, and it is easy to appear blind spots in drainage

In order to avoid the blind area of ​​drainage, it is necessary to re-upload the actual parameters of the drilling on the construction site, and move the drilling rig to take timely re-drilling measures for the actual blind area, which is not only time-consuming and labor-intensive, but also the actual parameters of the drilling are uploaded The graph adopts manual statistics, which has the defects of low statistical efficiency, large error and poor real-time performance
