Abstract

The invention relates to a coal mine safety monitoring system staged and sectional alarm method. The coal mine safety monitoring system staged and sectional alarm method comprises the following stepsthat hazard sources can be monitored by a monitoring system are listed; a risk level of the hazard sources is evaluated, and the hazard sources are divided into different stages according to the risklevel; a single hazard source warning criterion is set; according to the stages of the hazard sources, different weights are given, and a comprehensive staged warning criterion is set in combination with the single hazard source warning criterion; according to the comprehensive staged warning criterion, staged alarm is carried out; and system control measures for different warning stages are set.The coal mine safety monitoring system staged and sectional alarm method predicts the gas concentration of a coal mining face in advance, conducts gas outburst early warning on a tunneling working surface, and conducts alarm and power failure according to the staged alarm and power failure strategies; and when alarm occurs, voice audible and visual alarm are sent out, and short message notifications are sent to relevant personnel according to the staged alarm stages, so that the safety production management requirements are ensured.

Description

Technical field: [0001] The invention relates to the technical field of mine safety, in particular to a coal mine safety monitoring system hierarchical partition alarm method and a safety monitoring system. Background technique: [0002] The existing coal mine safety monitoring system only realizes the pre-alarm of a single parameter, does not consider the time factor of the data abnormality of the sensor monitoring, etc., and cannot fully meet the needs of mine safety production management. Therefore, a hierarchical and partitioned alarm method is proposed. When disasters or failures of different degrees occur, the function of sending alarm information to different levels of departments in different ways is realized. [0003] According to the theory of safety science and according to the role of hazards in the process of accident occurrence and development, hazards are divided into the first type of hazards and the second type of hazards. The first category of hazards refe...
