摘要
非洲马里缺水 ,需要大量水井。本文介绍了当地大口井掘进的传统施工方法 ,分析了其进度慢的原因。在就地取材等不利条件下 ,通过布置空心眼、掏槽眼和采用延时雷管 ,提高了爆破效率。最后 ,对安全生产和管理做了总结。
Water wells are largely required in Mali due to its insufficiency. The local traditional methods in well digging are presented in this paper. Their disavantages are discussed in terms of their slow speed in digging. After using local materals with empty holes, cutting holes and delayed-action detonators, the efficiency of blasting has been improved. Finally matters concerning safety production and manage are summarized.
