Coal mine safety management risk evaluation method

Abstract

The invention discloses a coal mine safety management risk evaluation method comprising the following steps: collecting original materials, and building a coal mine safety management risk database; analyzing and evaluating data information, and building a linear regression relationship according to the analysis and evaluation results; using a coal mine safety management system to emit safety detection signals, monitoring the production situation in a coal mine production system in real time, identifying unsafe factors in the coal mine production system, and issuing a warning in real time; rechecking located unsafe factors, determining the accident rate and accident risk degree of the unsafe factors, and determining the potential causes of accident; and avoiding risk in the actual process of coal mining. The coal mine safety management risk evaluation method has the advantages of good predictability, good integrity and high accuracy. The rate of risk avoidance is up to 99.3%. The method fills the gap in the aspect of coal mine safety management risk assessment methods, and is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of risk assessment, in particular to a risk assessment method for coal mine safety management. Background technique [0002] A coal mine is a reasonable space dug by humans when excavating a geological layer rich in coal, usually including roadways, wells and mining faces. Coal mining in China must be carried out in accordance with the law, and the licenses must be complete and valid. Implement the safety production policy of "safety first, prevention first, and comprehensive management". Despite this, the coal mining industry in my country still has the most accidents and the highest casualties except for the transportation industry. The number of casualties in accidents is nearly 10,000 every year, accounting for more than 60% of the domestic industrial deaths. In recent years, with the increase of coal mining depth, the safety of high-yield and high-efficiency mines has become a major issue that people ...
