Abstract

The invention provides a distributed monitoring system for the temperature of an underground filling body, and belongs to the technical field of paste filling and mining in mines. The distributed monitoring system comprises a temperature sensing optical fiber, a data collection system, an aluminum casing, heat conduction silicone grease, a sealant and the like, wherein the aluminum casing is located in a filling body drill hole; the temperature sensing optical fiber is put into the aluminum casing according to a requirement of the measurement length; the data collection system is located outside the filling body and connected with the temperature sensing optical fiber; the heat conduction silicone grease is located in the aluminum casing and wraps the temperature sensing optical fiber; andthe sealant is located at the outlet of the aluminum casing and mainly used for preventing heat dissipation at the junction. The distributed monitoring system can accurately monitor the temperature of the filling body at different positions and different hydration time at the same time, and can obtain real-time, online and continuous monitoring data, thereby providing an accurate basis for analyzing the paste performance.

Description

technical field [0001] The invention relates to the technical field of mine paste filling and mining, in particular to an underground filling temperature distributed monitoring system. Background technique [0002] Mine paste filling material is a toothpaste-like, non-bleeding plunger-like structural fluid composed of various bulk materials (cementing materials, tailings, fly ash, additives, etc.) and water. It is stable in nature and can be transported to the underground goaf through long-distance pipelines, and can form a certain strength to effectively support the surrounding rock, thereby controlling surface subsidence. Paste materials are the core of the entire paste filling mining technology, and the study of factors affecting various properties of materials plays a vital role in the promotion and development of paste technology. In recent years, many scientific researchers have carried out some basic experimental research on the performance changes of the paste under...
