矿井通风系统故障巷道规律分布
Fault roadway law distribution of mine ventilation system
摘要
Abstract
In order to build reliable mine ventilation system and ensure coal mine safety production,the failure roadways law distribution of ventilation system was researched,and the change regulations of roadways wind resistance was analyzed by using probability theory and mathematical statistics methods.In the case of Xiaoqing mine,mine roadway was divided into two categories:uniform distribution of fault roadway and the normal distribution of fault roadway,and failure probability function of mine roadway were defined.Based on probability density function,the function of judge ventilation failure was confirmed.The influence relationship of ventilation roadway failure and the whole ventilation system on Xiaoqing mine was researched.Results show that during the repair period,a single roadway failure probability is certain,and ventilation system is not faulty;when multiple roadways paralleled with a certain failure probability exist,ventilation system has fault and not fault of two possibilities.关键词
