摘　　要：在煤层中施工瓦斯卸压孔的过程中,瓦斯突然喷出会威胁到人员安全。针对现有防喷装置需要人工操作、反应慢的缺点,设计了一种电液联合控制的自动防喷控制系统,样品经现场试验表明,该自动防喷控制系统自动化程度高、封堵迅速,对钻孔过程出现的瓦斯喷出情况起到积极有效的防护作用。In the process of drilling gas pressure-relief hole in the coal seam, sudden discharge of the gas threatens the safety of construction personnel. In order to solve the shortcomings of the existing anti-spray devices, including manual control and slow reaction, an auto anti-spray control system which is controlled by electro-hydraulic technology is designed. It is verified by the field tests that the automation level of the system is very high and the plugging motion is very fast. As a result, it can provide a positive and effective protect when the gas snravs in the drilling process.
