Abstract

The invention discloses a pre-buried filling body lateral deformation measuring device, which belongs to the technical field of mine filling body monitoring. The pre-embedded filling body lateral deformation measuring device is buried in the filling body, and it is used to measure the left and right sides and the total lateral deformation of the filling body; it includes a measuring body, a steel pipe, an extension line and two pulleys fixed in the measuring body Rope displacement sensor, the measuring body includes a housing and an upper cover matching the housing, several sections of steel pipes are connected in the horizontal direction of the measuring body, adjacent steel pipes are connected end-to-end by threads, and part of the rope displacement sensor is pulled The ropes are all located in the steel pipe, and an extension line and a connecting ring are also arranged in the steel pipe. The extension line and the stay rope of the stay rope displacement sensor are fixedly connected through the connecting ring. Wear steel pipe inside. The pre-embedded filling body transverse deformation measuring device of the present invention can realize the measurement of the left and right sides and the total transverse deformation of the filling body.

Description

technical field [0001] The invention relates to the technical field of mine filling body monitoring, in particular to a pre-buried filling body transverse deformation measuring device. Background technique [0002] Filling mining refers to the use of filling materials to fill the goaf after underground coal resources are mined. The filling body can effectively support the overlying rock stratum, and the deformation value of the ground surface is controlled within the allowable deformation range of the building (structure). Safe recovery of coal resources under mines, and at the same time protect the ecological environment and groundwater resources in the mining area. Filling mining is an important technical method for mining "three-down" coal pressing in my country. In recent years, with the continuous improvement of environmental protection requirements in China, filling mining technology has been more and more widely used in my country. [0003] After filling and mining, ...
