露天深孔台阶爆破炮孔测量技术探讨

摘要

The inclination and depth of borehole are important factors to ensure blasting effect in the surface deep hole bench blasting. The workload of traditional measurement methods about borehole is extensive,which becomes a short board of digital blasting construction. Aiming at the above problems,the measurement method of artificial tape,sound wave and laser are discussed respectively based on borehole measurement experiment,including test principle,advantages and disadvantages,a-dapted condition and improvement measures of the three borehole measurement methods. The measurement methods based on sound wave and laser have the potential improvement and application space,and it can provide reference for the development of digital borehole measure in surface deep hole bench blasting.%在露天深孔台阶爆破中，炮孔的倾角和深度是保证爆破效果的重要因素，而传统炮孔测量方法工作量巨大，成为数字化爆破施工发展的短板。针对上述问题，并基于炮孔测量试验，分别论述了人工皮尺、声波、激光3种炮孔测量方法，包括3种炮孔测量方法的测试原理、优缺点、适应条件及相应的改进措施。其中基于声波和激光的炮孔测量方法具有潜在的改进和应用空间，可以为露天深孔台阶爆破数字测孔技术的发展提供借鉴。
