Abstract

The invention discloses a gypsum mine collapse monitoring system and a building method. The gypsum mine collapse monitoring system comprises drill holes, monitoring sensors, demodulation equipment, amonitoring platform and a buzzer; a plurality of drill holes are independently distributed in each monitoring position of a goaf; the monitoring sensors are arranged in the drill holes; the demodulation equipment is arranged in a safe area; the demodulation equipment is connected with the monitoring sensors and upload monitoring data to monitoring software of the monitoring platform so as to sendout a pre-judgment alarm; the buzzer is arranged at the ground surface position of a monitoring point and is connected with the demodulation equipment; the monitoring sensors comprise a fiber bragg grating displacement meter, a fiber bragg grating osmometer, a geological disaster alarm and a geophone; the buzzer gives an on-site alarm according to a geological disaster alarm signal; the monitoringsensors are used for monitoring multiple parameters of the geology of the goaf, so that collected data are comprehensive, all-around monitoring, pre-judgment alarming and field alarming are achievedat the same time, and an operator can be helped to rapidly take timely response measures according to dangerous geological conditions.

Description

technical field [0001] The invention relates to the technical field of gypsum mine subsidence monitoring, in particular to a gypsum mine subsidence monitoring system and an assembly method. Background technique [0002] Gypsum is a widely used industrial and construction raw material, mostly stored underground. China's gypsum resources are very rich and widely distributed, with a total reserve of more than 57.6 billion tons, ranking first in the world. With the advancement of urbanization in our country, the rapid development of the construction industry and decoration industry has provided a broad development space for the gypsum industry, and the market capacity has continued to expand. The large-scale mining of gypsum mines has brought economic benefits, but also left serious hidden dangers of goaf subsidence. Therefore, it is of great practical significance to carry out the monitoring work of the goaf in gypsum mines. [0003] Theodolite, level, steel ruler, distance g...
