Goaf collapse alarm device

Abstract

The invention discloses a goaf collapse warning device which comprises a ground warning flight part, a solar energy part, a walking part, a mechanical arm part and an underground detection part, the ground warning flight part is provided with a controller, and the walking part is controlled by the controller to drive equipment to move to a designated position for drilling detection; solar energy is converted into electric energy through the solar energy part to supply power to equipment. The underground detection part is clamped by the mechanical arm part to be drilled into the ground; variousunderground data of the goaf are detected in real time through the underground detection part; when collapse is about to happen, the ground warning flight part rapidly flies to flicker the alarm lampand gives out alarm sound through the alarm loudspeaker, and casualties and economic losses of personnel are reduced. After collapse is finished, the underground detection part automatically returnsto the ground to complete equipment recycling, the detection cost is reduced, the danger of manual operation is avoided, and the equipment completes integration of goaf detection, collapse warning andequipment recycling.

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...
