Device for controlling and locking blast firing in real time under coal mine well and method thereof

Abstract

The invention discloses a device for controlling and locking blast firing in real time under a coal mine well, which comprises a central controller, a plurality of sub-controllers, a card reader, an identification card and a blasting fire locking device. The method for controlling and locking blast firing in real time under a coal mine well concretely comprises the following steps: 1) detecting whether a blasting machine connects to a system or not; 2) judging position information of underground work staffs who carry the identification card, turning to the step 4) if the underground work staffs are on the job, and turning to the step 3) if the work staffs are in absence of job or in a dangerous area; 3) sending out a locking instruction and stopping a blast firing work; and 4) unlocking the blasting machine to carry out the blast firing. The device can monitor the position information of work staffs in the blast firing area, the blast firing work is controlled, and the safety of blast firing work staffs can be guaranteed.

Description

technical field [0001] The invention relates to an underground coal mine management control device and a method thereof, in particular to a management control device and a method for blasting operation in a mine. Background technique [0002] At present, there are blasting operations in coal mines, which are mainly divided into two categories: one type uses a blaster plus an alarm mode, the device is activated when blasting, the blaster supplies power to the alarm, the alarm senses light, and an alarm is issued when a light signal is found; the other The explosion-proof blasting lock control box is used in this category, combined with the personnel management system, a card reader is arranged in the roadway of the blasting area, and the card reader is only used during the blasting operation to judge the passage of personnel. These two types of devices have the following disadvantages: [0003] 1. It is impossible to dynamically and real-time count the personnel data informa...

AI Technical Summary

Problems solved by technology

[0003] 1. It is impossible to dynamically and real-time count the personnel data information during the blasting operation, and to lock and control the detonator, so that when there are personnel in the area who want to evacuate, they cannot be found in time, causing accidents;

[0004] 2. It is impossible to detect and judge the directionality of people entering and leaving the blasting area in real time, and count the number of people in the blasting area;

[0005] 3. During the whole blasting operation process, it is impossible to make real-time dynamic statistics on the availability of guard personnel, tile inspectors, blasting personnel and team leaders;

[0006] 4. It is impossible to monitor and upload detailed information such as personnel presence, personnel evacuation, and device operation to the ground central controller in real time during the underground blasting operation, which is not convenient for the central controller to manage and control;

[0007] 5. The function of forced unlocking cannot be performed on the ground, and emergency situations cannot be handled;

[0008] 6. The status of the equipment cannot be monitored in real time, and the alarm cannot be implemented immediately if the equipment failure is found
