A goaf subsidence alarm device

Abstract

The invention discloses a goaf subsidence alarm device, comprising: a ground alarm flight part, a solar energy part, a walking part, a mechanical arm part, and an underground detection part. The ground alarm flight part is equipped with a controller, and the walking part is controlled by the controller to drive equipment Move to the designated location for drilling detection; use the solar part to convert solar energy into electrical energy to power the equipment; use the mechanical arm to clamp the underground detection part to drill into the ground; use the underground detection part to detect various data in the gob underground in real time ; When a collapse is about to occur, the ground warning flight part flies quickly to flash the warning light and simultaneously sends out the warning sound through the warning loudspeaker to reduce casualties and economic losses; The cost of detection is reduced, and the danger of manual operation is avoided. This equipment completes the integration of goaf detection, collapse alarm and equipment recovery.

Description

technical field [0001] The invention relates to the technical field of mining area equipment, in particular to a goaf subsidence alarm device. Background technique [0002] The hazards of underground mined-out areas to mining projects are significant and cumulatively superimposed, mainly reflected in two aspects: one is the deformation and destruction of ore pillars in the mined-out area, large-scale caving of the roof, and rock movement, resulting in surface subsidence, cracking and subsidence , damage the ground environment and affect open-pit operations, and what is more serious is the casualties and equipment damage caused by the high-speed air waves and shock waves of the sudden collapse of the goaf; The impact leads to the development of cracks in the rock mass, and even penetrates the surface or connects to the accumulated water in old kilns, causing water inrush accidents, submerging tunnels and working faces, and causing huge economic losses. [0003] Because the u...
