Description

technical field [0001] The invention discloses a coal mine gas drainage drilling monitoring and management system, which belongs to the technical field of gas drainage safety production. Background technique [0002] Coal seam drilling pre-extraction of gas is an important part of the daily work of coal and gas outburst mines. At present, a single manual supervision method is generally used in drilling construction, which cannot effectively prevent false drilling and false footage reporting, etc., resulting in accidents due to inadequate implementation of gas control measures. In recent years, with the increase of production and the development of mining deployment to the deep, the amount of gas control projects has continued to increase. Regarding the safe production of coal mines, the construction quality of drilling and sealing holes in gas drilling sites directly affects the effect of gas control. Inconsistent drilling parameters and poor sealing effect will seriously a...

AI Technical Summary

Problems solved by technology

[0003] 1. Drilling needs to be stopped during the daily maintenance time and the time for the excavation team to enter and discharge materials. After the normal drilling is resumed, the hole forming time is relatively concentrated, and the acceptance efficiency is low, which affects the construction efficiency

[0004] 2. Due to the large amount of extraction drilling footage and multiple drilling locations, drilling acceptance personnel are assigned as needed, and at least one acceptance personnel is guaranteed for each drilling location. The focus is on the inspection and acceptance of drilling footage, but it is impossible to achieve full tracking acceptance

[0005] 3. As the mining activities gradually extend downwards, the gas content increases and the drilling difficulty increases

In order to pursue economic income, the operating personnel may not reach the design depth, which affects the hole forming rate

[0006] 4. There is a phenomenon that drilling personnel do not hand over shifts at the designated location, the utilization rate of working hours is low, and there are certain safety hazards

[0007] 5. When there are changes in the drilling site, such as spray hole, top drill, stuck drill, drill pipe drop, equipment failure, etc., it should be dealt with according to the change classification response process, and the operator needs to wait for the relevant personnel on site, which has poor timeliness
