【摘要】 从爆破位置筛选、爆破装置设计、爆破效果评价等方面,系统地研究了超深温泉井爆破增加流量关键技术。设计了一种加工方便、成本低廉、安全可靠的防水耐高压深井爆破筒及其配套的爆破装置系统,并利用该系统在温泉井内呈破碎带或非闭合裂隙处爆破,导通地下水源地与温泉井间的屏障,从而增加温泉井的涌水量,达到高效开采深部温泉资源的目的。更多还原

【Abstract】 The technology of increasing flow rate of warm spring by blasting in the deep well was discussed from three aspects,including selection of blasting zone,design of blasting equipments and evaluation of blasting effect.To better exploit warm spring in deep area,the bangalore of pressure type and the matched equipment system were designed with convenience,low cost and safety.By using this system,blasting in the fracture zone or the area with nonclosed fracture in the warm spring well was achieved.Fractures were extended in the rock and then obstacles between the water source region and the warm spring well were cleared up.The flow rate of most of the spring well was increased obviously after blasting,and high efficient mining deep warm spring resource was achieved.更多还原
