A filling body deformation on-line monitoring system and its monitoring method

Abstract

The invention discloses a filling body deformation online monitoring system and a monitoring method thereof, and relates to the technical field of mine filling body monitoring. It includes an extension part, a fixing device, a filling body lateral displacement measuring device, a filling body vertical displacement measuring device, a baffle, a steel pipe, an extension line, a data transmission line, a communication substation, a communication master station, a telephone line, a data acquisition instrument and a computer system, the filling body lateral displacement measuring device and the filling body vertical displacement measuring device are installed at the measuring points in the filling body; the filling body lateral displacement measuring device is arranged along the horizontal direction, and the filling body vertical displacement measuring device is arranged along the vertical direction; The bottom of the filling body vertical displacement measuring device is fixed by the fixing device, and the extension part is installed above the filling body vertical displacement measuring device, and the top of the extension part contacts the top plate of the area to be filled. The invention can realize real-time, on-line remote monitoring of the lateral deformation and vertical deformation of the filling body.

Description

technical field [0001] The invention relates to the technical field of mine filling body monitoring, in particular to an online monitoring system for filling body deformation and a monitoring method thereof. 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] Aft...
