Abstract:

The complexity and interactive of activities between the subjects in the coal mine production system determines that the “group” is the key subject to protect safety production in coal mines in working order. This paper introduced the symbiosis theory to study the groups in safety management in coal mines. The peer groups and hierarchy groups were considered further with the characteristic parameter of the symbiosis theory, such as the symbiotic environment, symbiotic interface, and symbiotic degree and so on, to analyze the interaction mechanism between both symbionts. At the same time, the safety symbiotic model of coal mine groups was built combining the correlation function of the symbiosis force and competitive force, while the symbiotic optimization path was obtained through the stability analysis of symbiosis function (symbiotic state/safety order: mutual harm/danger zone-strong partial benefit/risk area-weak partial benefit /rehabilitation area-mutually benefit/sub health area-strong mutually benefit/health area). Based on the field research, the symbiotic initial value of current coal mine groups was obtained. MATLAB numerical analysis indicate that at present, both the peer groups and the hierarchy groups do not reach the state of good mutualism while the hierarchy groups is in a commensalism status under the current situation. Moreover, when the symbiotic degree of both symbiotic units is improved simultaneously, their overall safety level tends to be optimized. Apart from that, when the symbiosis environment and symbiosis interface are improved, and the competitiveness is reduced, the evolution of overall safety level tends to be more optimized. This paper offers a new perspective for coal mine safety management from the symbiotic relationship of groups and provides reference for safety management in other areas.
