Multifunctional monitoring device for mining subsidence land damage in coal mine area

Abstract

The invention discloses a multifunctional monitoring device for mining subsidence land damage in a coal mine area. The multifunctional monitoring device comprises fixed rods, a support plate, a telescopic rod, a casing and a mounting plate. The bottom of the support plate is evenly provided with the fixed rods. The center of the top of the support plate is provided with the telescopic rod througha first fixed sleeve. The telescopic rod is uniformly provided with limiting holes. The telescopic rod is provided with the casing through a mounting sleeve. A first installation chamber is arrangedin the casing. The bottom surface in the first installation chamber is provided with a host. The multifunctional monitoring device is composed of the fixed rods, the support plate, the telescopic rod,the casing and the mounting plate. Through the telescopic rod, the device height can be adjusted according to the environment or physical truth. A soil moisture detecting probe can detect the moisture inside the soil. Through a soil detecting probe, the device can detect the soil quality in the subsidence area. An infrared distance meter can carry out vertical detection in the subsided area, hasstrong practicability and is worthy of promotion.

Description

technical field [0001] The invention relates to the field of land damage monitoring devices, in particular to a multifunctional monitoring device for mining subsidence land damage in coal mining areas. Background technique [0002] China is a big consumer of coal resources. Coal resources account for about 70% of China's primary energy consumption. The mining of coal resources will inevitably cause land resources to be subsided, damaged, and occupied in varying degrees. The damaged land needs to pass through land Reclamation and other measures to restore it to its original state and productivity level. Among them, the damage characteristics, degree of damage and distribution of the land are the most important basis for choosing reclamation techniques and measures. Due to the different coal resources in various regions Occurrence conditions are different, the mining technology adopted in the mining process is also different, and the damage characteristics of the land are also...

AI Technical Summary

Problems solved by technology

[0002] my country is a big consumer of coal resources. Coal resources account for about 70% of my country's primary energy consumption. The mining of coal resources will inevitably cause land resources to be subsided, damaged, and occupied in varying degrees. The damaged land needs to pass through land Reclamation and other measures to restore it to its original state and productivity level. Among them, the damage characteristics, degree of damage and distribution of the land are the most important basis for choosing reclamation techniques and measures. Due to the different coal resources in various regions Occurrence conditions are different, the mining technology adopted in the mining process is also different, and the damage characteristics of the land are also quite different, so it is necessary to monitor the mining subsidence area through the corresponding land damage monitoring device, but the existing land damage The monitoring device is relatively lacking, the function is relatively single, and there are many deficiencies in the operation. Although the traditional land monitoring has achieved the basic operation purpose, it only has a single monitoring function and cannot monitor multiple aspects at the same time. The operating performance of the device is reduced. At the same time, the traditional monitoring device requires staff to perform auxiliary operations during operation, which not only increases the labor force, but also reduces the practicability of the device and increases the limitations.
