摘　　要：为了高效开采深部温泉资源,通过系列试验论证并设计了一种加工方便、成本低廉、安全可靠的专用防水耐高压深井爆破筒。利用该爆破筒在温泉井内破碎带或非闭合裂隙处进行爆破,从而导通地下水源地与温泉井间的屏障,提高超深温泉井的涌水量。实践证明,以该防水耐压爆破筒为核心的专项爆破技术,安全可靠、经济高效。In order to study deep hot spring resources efficiently,a series of tests were performed in designing the pressure-type Bangalore,for the convenience,low cost,safety and reliability. The special Bangalore was initiated in the fracture zone or the area with non closed fracture in the hot spring well,which extended fractures in the rock and then cleared up the obstacle between the water source region and the hot spring well. Finally,the flow rate of the spring well increased. Experiences showed that the special blasting technology with designed pressure-type Bangalore in deep hot spring resources was safe and efficient.
