Abstract

A gob-side entry retaining pasty filler on-line detection method comprises the steps that before each monitored space is ready to be filled, supporting rods are fixed to a base plate of a space to be filled through ground anchors, the upper ends of the supporting rods support a top plate of the space to be filled, measuring optical fibers are arranged between the supporting rods, an optical fiber connector is introduced out of the tail portion of the last supporting rod in each set of supporting rods and is connected in a mining optical cable through optical fibers so that optical fiber monitoring signals can be transmitted to a distributed optical fiber demodulator, demodulated signals are transmitted to a computer system, and pasty filler is monitored in real time on line and is analyzed and processed after the space is filled. The gob-side entry retaining pasty filler on-line detection method has the advantages that equipment installation is easy, the method is suitable for being universally popularized, no power supply is needed under a well, a site is safe, all-optical measurement and optical fiber transmission are adopted, influences caused by electromagnetic interference are effectively avoided, a monitoring result can be provided in time, and the method is favorable for directing on-site filling mining production work.

Description

technical field [0001] The invention relates to the technical field of gob-side entry retaining filling technology in mines, and more specifically relates to an online detection method for paste filling bodies in gob-side entry retaining. Background technique [0002] Filling mining technology is a major innovation in coal mining technology as a solution to coal mining under buildings, under railways, under water bodies and above confined water. [0003] Among them, an important part of the paste-filled coal mine green mining technology, the coal gangue, fly ash, industrial slag, inferior soil, urban solid waste, etc. near the coal mine are processed on the ground into a toothpaste-like slurry that does not require dehydration. , using filling pumps or gravity pressurization, transported to the underground through pipelines, filling goafs or abscission areas in a timely manner, forming an overlying rock support system mainly composed of paste fillings, and effectively contro...
