Abstract

The invention discloses an online monitoring system and method of transverse deformation of a filling body, and belongs to the technical field of mine filling body monitoring. The system comprises a bidirectional displacement measuring device, a data transmission line, a fixed disc, a communication substation, a communication main station, a telephone line, a ground data acquisition instrument anda computer system. The bidirectional displacement measuring device is buried in the filling body and used for measuring a left side, a right side and total transverse deformation of the filling body;the bidirectional displacement measuring device comprises a measuring main body, extension lines, steel pipes and two pull rope displacement sensors fixed in the measuring main body; and the measuring main body comprises a shell and an upper cover matched with the shell, the steel pipes are connected in the horizontal direction of the measuring main body, the adjacent steel pipes are connected end to end through threads, parts of the pull ropes of the pull rope displacement sensors are located in the steel pipes, and connecting rings and the extension lines are arranged in the steel pipes. Real-time and on-line remote monitoring of the left side, the right side and the total transverse deformation of the filling body can be achieved.

Description

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