摘 要:目前,矿井主通风机倒机的同时,风会暂时停止,虽然风停止的时间很短,但这段时间瓦斯超出最大限制含量的可能性仍然很大,按照《煤矿安全规程》第一百二十一条规定,必须采取措施防患于未然。该文设计了一种新型的矿井通风机倒机方案,该方案的应用实践表明,应用该方案以后,倒机过程风速下降幅度大大减小,下降持续的时间大大缩短,倒机过程中井下瓦斯含量升高幅度非常小,完全可以满足高瓦斯矿井的通风需求。At present,when the main fan of the mine is switched over,the wind will stop temporarily.Although the time of wind stop is very short,the possibility of gas exceeding the maximum limit content is still very large during this time.According to 121th item of the 《coal mine safety regulations》,it is necessary to take measures to prevent the disaster.In this paper,a new scheme of mine fan reversing is designed.The application of the scheme shows that after the application of the scheme,the decrease of wind speed in the process of reversing is greatly reduced,and the duration of the decrease is greatly shortened.The increase of underground gas content is very small in the process of reversing,which can fully meet the ventilation demand of high gas mine.
