Analysis On Ventilation System Stability After West Shaft Put Into Use Of Chengjiao Coal Mine

Ventilation system is an important part of the production system in mine. It plays a key role in ensuring normal production and disaster prevention. Mine ventilation system is a complex and dynamic system and its stability is affected by many factors. As the stability concerns with the normal production and workers' life safety, it is of great significance to study the stability of mine ventilation system.This paper summarizes former research achievements on ventilation system stability by a large number of scholars at home and abroad, and presents the existent insufficiency that exists in the current research, determines the content of this paper, thus makes the technical line. In this paper, the basic theory of ventilation system stability has been introduced systematically, also the ventilation system characteristics and the various factors that influence the stability of mine ventilation system has been analyzed in detail; Ventilation network calculating software has been used in Chengjiao mine, according to the measure of resistance condition before the transfixion of west air shaft; Combining with ventilation network solution and the actual situation of production in Chengjiao mine, four feasible schemes has been put forward; Through the analysis and demonstration of the scheme, comparing with effect verification and the measure of resistance after the transfixion of west air shaft, some correlative conclusions about the stability conditions of ventilation system has been obtained. Practice has proved that it is feasible and effective, and it has a great practical significance in mine production.
