A coal mine roadway roof fall disaster monitoring and early warning device

Abstract

The invention discloses a coal mine roadway roof fall disaster monitoring and early warning device, relates to the technical field of roadway roof fall disaster monitoring and early warning, and solves the problem of roadway roof fall disaster early warning. A coal mine roadway roof fall disaster monitoring and early warning device, including a main structure, the main structure has two groups, each group has two, installed symmetrically, the lower end surface of the main structure is installed with a foundation, and one side of the foundation is installed There is a load-bearing plate, and a fixing mechanism is installed in front of the two main structures. The upper end surface of the fixing mechanism is installed with a detection mechanism protection cylinder, and the upper end surface of the detection mechanism protection cylinder is installed with a quality inspection mechanism. The main structure includes: Prefabricated side panels, limiting edges, prefabricated top panels, matching card slots, inner support plates, fastening bolts, connecting bases, T-shaped slots and reinforcing ribs, there are two prefabricated side panels, and the upper end surface of the prefabricated side panels It is provided with matching card slots. The invention enables the device to have the function of early warning of mine tunnel collapse disaster and the function of isolating hazards.

Description

technical field [0001] The invention relates to the technical field of coal mine roadway roof fall monitoring and early warning, in particular to a coal mine roadway roof fall disaster monitoring and early warning device. Background technique [0002] With the rapid development of the mining industry, the requirements for mine roadways are getting higher and higher, and the factors that aggravate the hidden dangers of roof fall in the roadway are also increasing. The increase of the mine pressure leads to the increase of the mine pressure; the increase of the mine pressure and the complex geological conditions make the support more difficult. Therefore, the monitoring and early warning of roadway roof fall is very important. [0003] However, the existing roof fall disaster monitoring and early warning structure is single, the function is insufficient, and it cannot provide early warning and alarm in time to help evacuation. When in use, it cannot fix the inner wall of the ...
