Coal mine gas disaster monitoring and pre-warning system and pre-warning method

Abstract

The invention relates to a coal mine gas disaster monitoring and pre-warning system and a pre-warning method. According to the system and the method, automatic monitoring, transmission, real-time acquisition, storage and dynamic sharing of coal mine gas disaster related safety information are firstly achieved through a gas disaster safety information acquisition platform; then, deep mining and analysis are conducted on the related safety information by utilizing the gas disaster safety information acquisition platform according to gas disaster monitoring and pre-warning indexes and rules established on the four aspects of objective dangerousness, precautionary measure defects, management measure defects and catastrophe control, gas disaster danger level and range are automatically judged, and pre-warning results of different levels are issued in sound, light, short message and network forms and the like; finally, emergency linkage control of a coal mine power monitoring system, an underground personnel location system, an underground broadcasting system, an online ventilation monitoring system and other coal mine monitoring systems is achieved by utilizing a pre-warning linkage control software system according to the issued pre-warning results, and finally the purposes of online monitoring, real-time analysis and intelligent pre-warning and linkage control of coal mine gas disasters are achieved.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety, and relates to a coal mine gas disaster monitoring and early warning system and an early warning method. Background technique [0002] my country's resources are "rich in coal, poor in oil, and low in gas". The status of coal as the main energy source in my country will not be changed for a long time in the future, and it will still account for more than 50% of my country's primary energy structure. The Outline of Medium and Long-term Energy Development Plan (2004-2020) has determined that China will "adhere to the energy strategy with coal as the main body, electricity as the center, and comprehensive development of oil, gas and new energy", but the formation and occurrence of coal seams in my country The complexity determines that coal mine disasters are objectively very serious, and gas disasters are particularly prominent, which is the main threat to mine safety production in my countr...

Problems solved by technology

However, due to the many factors affecting gas disasters, the mechanism of occurrence is complex, and due to the gradual increase in mining depth and mining intensity, gas disasters are becoming more and more difficult to control, and the safety production situation is still severe

[0003] Forecasting and early warning is the primary link in the prevention and control of gas disasters. At present, most mines adopt a few static indicators (for example, the outburst prediction mainly uses structure, gas, soft stratification, K 1 , q, amount of drilling cuttings, etc.) to carry out risk prediction, there are problems such as single index, non-dynamic time, discontinuous space, etc., and the analysis of hidden danger information is not deep and timely enough, resulting in low prediction accuracy; at the same time Although the original coal mine monitoring and monitoring system has played a role in reducing the occurrence of gas accidents to a certain extent, there are still many immature and imperfect places in general. The monitoring system can only simply convert and store the original data. , display and printing, data resource mining and analysis are not deep enough, and major disaster hidden dangers cannot be discovered in time. The early warning function of the entire system is not strong, basically staying at the level of alarm rather than early warning; An important factor for the frequent occurrence of gas accidents. At present, the extensive management mainly relies on manual supervision and inspection, which cannot meet the requirements of proper management, and there is still a certain gap with the advanced management concept of refinement and process.

Therefore, comprehensively considering many influencing factors of gas disasters, comprehensive real-time analysis and early warning of potential safety hazards is the development trend of coal mine gas disaster prevention and control. Based on this, some mines have established single-factor early warning systems and comprehensive early warning systems, which provide important for mine gas prevention and control. However, there are still problems such as low automation level of gas safety information monitoring and collection, imperfect early warning indicators and models, and inability to carry out linkage control.
