A detection device for rock movement and surface subsidence in thick loose layer mining

Abstract

The invention belongs to the technical field of surface subsidence detection, and specifically relates to a detection device for rock movement and surface subsidence in thick loose layer mining; it includes a subsidence detection unit and a detection and observation unit; the subsidence detection unit is arranged according to the coal mine measurement and design manual; a conical pile core The bottom of the hollow fixed pile is located at the bottom of the hollow fixed pile through the sealing collar, and the top of the conical pile core is connected with a rubber float; the side wall of the sliding chamber is provided with a water guide chamber, and the water guide chamber is located between the rubber float and the seal. Between the rings; the transparent baffle evenly divides the glass detection water tank into multiple water storage chambers, and the bottom ends of the multiple water storage chambers are respectively connected with the water guide chambers set on the multiple hollow fixing piles through the water guide pipes; Through the setting of the subsidence detection unit and the detection and observation unit, it is possible to accurately detect in real time whether the rock layer in the coal mining area has collapsed or moved, so that the detection personnel can carry out targeted security protection for the rock layer in the coal mine area.

Description

Technical field [0001] The present invention belongs to the field of surface subsidence detection, and is specifically a thickness-striped layer mined rock formation movement and surface sink detection device. Background technique [0002] Coal mine summer surface sinks have seriously undermined the monitoring and control of surface subsidence in the mining area, and the monitoring and control of surface subsidence has become an important measures for environmental governance in mining areas. The real-time monitoring of surface seventh regularization is an important means of surging and controlling control and environmental assessment in the air area. . [0003] Mining Table Subsidence is an important measures to ensure the safety of ground well shelves, winch buildings and other buildings, structures, etc., and the mine surface sink is in a long time in dynamic excavation disturbance, how to do long-term, effective and accurate surface monitoring, is A problem that mine enterpri...

AI Technical Summary

Problems solved by technology

[0005] In the contact measurement method, regular monitoring of fixed points on the surface is carried out through the buried point, which is a common monitoring method today. The traditional buried method is buried with concrete piles, and this traditional concrete buried detection method is difficult to detect accurately. When the coal mine is being mined, the movement or subsidence of the rock layer area makes it difficult to effectively support the rock layer after mining, which leads to the collapse and subsidence of the surface layer
