SP-V型水炮的研究设计

Study and Design of the SP-V Water Canon

目前，我国绝大部分煤与瓦斯突出矿井的煤巷掘进均采用超前钻孔为主的局部防突安全技术措施。多年来的生产实践表明，这种方法存在着施工安全性差；打孔进度慢；工作面瓦斯浓度较高的环境中因有电器设备，一旦失爆有可能引燃引爆瓦斯等问题。利用脉冲射流水炮打超前卸压孔，可实现工作面无人无电作业，对保障工人人身安全、改善劳动条件、加快掘进速度、提高劳动生产率，都有重要的现实意义。文中对SP－V型水炮的设计思想、工作原理、结构设计特点、使用性能等分别进行了介绍。

In the majority of the coal mines suscoptible to gas outburst hazards,the coal drifts are generally driven with local gas outburst protection method through drilling advance gas release boreholes. Experience shows that this method has inberent drawbacks of being unsafe and slow in progress,etc. Use of pulsed waterjet canon to drill advance gas release boreholes can lead to greater personal safety, improved working condition,higher drivage speed and higher labour productivity. A description is made of the design concept, operating principle, structural features and technieal performance of the canon developed.
