我国煤矿安全问题一直是制约煤矿行业生产发展的重要因素,而瓦斯含量过高则是发生矿井下事故的主要原因。因此,为了促进煤矿企业的健康发展,就要做好矿井下的安全管理工作。其中,瓦斯通风防治工作对于确保煤矿的安全生产至关重要,通风既可以及时排除煤矿回采中排出的瓦斯,还可以稀释煤尘,从而确保生产安全。本文结合实际从作用原理、注意事项等方面,对B型通风技术和均压通风技术两种高瓦斯矿井下的通风防治技术进行分析。
Coal mine safety in our country has always been an important factor restricting the production and development of the coal mining industry. However, the excessive gas content is the main reason for accidents in the mine. Therefore, in order to promote the healthy development of coal mining enterprises, we must do a good job under the mine safety management. Among them, the prevention and control of methane ventilation is essential to ensure the safe production of coal mines. Ventilation can both eliminate the gas discharged from coal mines in time and can also dilute the dust so as to ensure the safety of production. This article analyzes the ventilation control technology under two kinds of high-gas mines, such as B-type ventilation technology and pressure equalization ventilation technology, from the aspects of operation principle and precautions.
