Goaf underground water level monitoring and early warning device and early warning method thereof

Abstract

The invention, which belongs to the technical field of underground water level monitoring, discloses a goaf underground water level monitoring and early warning device and an early warning method thereof. The goaf underground water level monitoring and early warning device comprises an underground well; and two cavities are formed in the inner wall of the underground well in a bilateral symmetry mode. A plurality of groups of first conductive blocks are arranged on the inner wall of the underground well up and down; each first conductive block is connected with a fixed rod; the plurality of fixed rods on the two sides are communicated with the cavities on the two sides; two limiting rods are arranged in the underground well front and back; the two limiting rods are vertically arranged in parallel; the limiting rods are sleeved with floating blocks, the left end and the right end of each floating block are provided with two second conductive blocks, and the two second conductive blocksare connected through a wire. A support is arranged on the upper side of the underground well and is provided with a plurality of alarm indicator lamps and a buzzer alarm; and the support is further provided with a storage battery. Alarming can be conducted on water levels of different heights in the underground well; the structure is simple, the cost is low, and the early-warning alarm effect isgood.

Description

technical field [0001] The invention relates to the technical field of groundwater level monitoring, and more specifically relates to a groundwater level monitoring and early warning device for a goaf and an early warning method thereof. Background technique [0002] The goaf is a "hole" created by man-made excavation or natural geological movement below the surface. The existence of the goaf makes the safe production of the mine face a great safety problem. Personnel and mechanical equipment may fall into the goaf and be damaged. harm. There are three definitions of groundwater: one refers to all the water buried in groundwater that is significantly different from surface water, especially that part of the water in the saturated zone of the aquifer; The water that supplies springs and wells; the third is the water stored in the underground rock cavities and in the interstices of the materials that make up the earth's crust.

AI Technical Summary

Problems solved by technology

[0003] There is often groundwater inside the goaf. Due to the fluidity of water, the groundwater level in the goaf will continue to rise. The underground goaf has strong concealment, poor spatial distribution characteristics, and the collapse of the goaf roof is difficult to predict. Therefore, it is necessary to monitor the groundwater level in the goaf. The existing monitoring devices generally have the disadvantages of poor monitoring effect, complex structure and high cost.
