A multi-parameter comprehensive intelligent monitoring method for mining roadway

Abstract

The invention discloses a multi-parameter comprehensive intelligent monitoring method for a mining roadway. Specifically, a series of monitoring sections are established in the mining roadway of a coal mining face, and a variety of sensors are arranged in the monitoring sections to detect displacement, stress, gas, temperature, Changes in indicators such as dust and personnel positioning; set up a data monitoring sub-station at the entrance of the mining roadway, collect the data monitored by each sensor, and upload the collected data to the data collection sub-station, and the data collection sub-station will then upload it to the ground monitoring service through signal conversion Center, the ground monitoring service center is responsible for judging whether the received data is within the preset safety threshold, timely adjusting the layout of the underground support body, and monitoring again until the monitoring indicators are within the safety threshold and meet the roadway service requirements. The invention solves the problems of large errors and low monitoring efficiency in traditional manual monitoring, realizes multi-section, full-time and space-time, unmanned intelligent monitoring, and significantly improves the accuracy and efficiency of monitoring.

Description

technical field [0001] The invention relates to the field of coal mine roadway safety monitoring, in particular to a multi-parameter comprehensive intelligent monitoring method for mining roadways. Background technique [0002] With the continuous acceleration of the intelligent process of my country's coal industry and the deepening of the complexity of coal mining conditions, the emphasis on the safety of mining roadways in working faces is also increasing. During the coal mining process, the mining roadway is responsible for important functions such as coal transportation, material transportation and ventilation of the entire working face, and its safety status directly affects the safe operation of the entire coal mine. For a long time, many risk factors of the mining roadway have been threatening the safety of the mining roadway all the time, but this has also become an important indicator for monitoring the safety of the roadway. Among them, the displacement stress cr...

Problems solved by technology

[0003] At present, a variety of measurement devices and methods have been widely used, but manual measurement is still the main method in the measurement process. Errors and improper operation cause measurement errors, etc., which cannot truly and comprehensively reflect the actual conditions of the various parameters of the roadway, and large-scale long-term monitoring will consume a lot of manpower and material resources, resulting in a sharp increase in costs, which cannot meet the goal of intelligent development of coal mines

Therefore, there is a lack of an intelligent, easy-to-operate, high-accuracy, and systematic monitoring system for monitoring and early warning of various parameters of underground mining roadways
