Multi-terminal parameter monitoring system for coal mine underground tunnel drilling rig

Abstract

The invention relates to a multi-terminal parameter monitoring system for a coal mine underground tunnel drilling rig. The multi-terminal parameter monitoring system for the coal mine underground tunnel drilling rig comprises a sensor component, a field control box and a display terminal component. The sensor component is disposed on a tunnel drilling rig body. The field control box is disposed on the tunnel drilling rig body. One side of the field control box is connected with the sensor component, and the other side of the field control box is connected with the display terminal component. The field control box processes electrical signals acquired by the sensor component into multiple optical signals transmitted to the display terminal component. The multi-terminal parameter monitoring system for the coal mine underground tunnel drilling rig is applicable to coal mine underground work environments, is convenient to mount and low in cost, has far monitoring range, multiple display terminals and flexible display ways, and is capable of monitoring multiple drilling parameters of the drilling rig in real time to assist drillers in finishing downhole drilling.

Description

technical field [0001] The invention belongs to electronic instruments and meters in underground coal mines, and in particular relates to a multi-terminal parameter monitoring system for underground tunnel drilling rigs in coal mines. Background technique [0002] my country is a large coal-based energy consumption country. Almost 95% of coal resources come from underground mining. Due to the complex and changeable coal seam occurrence conditions in my country, gas explosions, coal and gas outbursts, roof caving, water seepage and other dynamic forces Disasters and accidents happen frequently. The underground coal mine is a special production environment with high humidity, large dust and explosive gas. With the gradual mining of high-risk resources such as deep and soft outburst coal seams in my country, the working conditions in the mine are becoming more and more complex, and the safety threats to operators are becoming more and more serious. [0003] Gas drainage is the...

Problems solved by technology

[0003] Gas drainage is the basic way to prevent and control gas disasters in coal mines. It is mainly realized through coal seam drilling. At present, the underground drilling construction of coal mines in my country is mainly based on full-hydraulic power head drilling rigs, which are usually driven by motors. The rotation and feeding of the power head are controlled by the hydraulic system, and then the drill bit is driven to cut coal and rock. During drilling, the driller needs to know the drilling working status according to various instruments equipped on the drilling rig, such as pressure gauges and thermometers, and then According to the experience of operating the drilling rig, this construction method requires the driller to be located near the drilling rig, and it is difficult to avoid personal injury caused by coal seam drilling outburst accidents
