Pressing multi -parameter process monitoring system and early warning method

Abstract

Provided are a monitoring system and an early warning method for a rock burst multi-parameter process. The method comprises the steps that (1) a mining activity peripheral region is monitored in a traditional rock burst monitoring method, and a dangerous region is determined; (2) sensing elements are distributed in the dangerous region; (3) the sensing elements are in wired connection with data communication base stations; (4) the data communication base stations are in wired connection with the adjacent data communication base stations and switching equipment; (5) the switching equipment is connected with an analyzing and processing unit through an optical fiber; (6) after the sensing elements start to work, collected data are transferred to the analyzing and processing unit through the data communication base stations and the switching equipment; (7) the analyzing and processing unit stores and analyzes the received data, and early warning of occurrence of rock burst is achieved according to comparison between the data and a preset danger index value. The monitoring system comprises more than two sensing elements, more than two data communication base stations, the switching equipment and the analyzing and processing unit. The early warning method and the monitoring system are low in cost, flexible in layout, and good in early warning effect.

Description

technical field [0001] The invention relates to a disaster early warning method and a monitoring system, in particular to a multi-parameter process early warning method and monitoring system of rock burst. Background technique [0002] The phenomenon of rock burst disaster is a major dynamic disaster accident in the process of coal mining. In recent decades, experts and scholars at home and abroad have achieved positive results through in-depth research on the mechanism of rock burst, and made many positive contributions to reducing casualties and economic losses caused by rock burst disasters. This is mainly reflected in domestic Foreign experts and scholars have proposed many prediction methods of rock burst based on their research results. [0003] These prediction methods mainly include: microseismic and ground sound (acoustic emission) method, drilling cuttings method and electromagnetic radiation method, etc. However, the above-mentioned rock burst prediction methods...
