Optimization of Medium and Deep Hole Blasting Parameters and Blasting Effect Control Technology

摘要

中深孔爆破作为矿山开采、基建施工等工程领域的核心技术，其参数设计的科学性直接决定爆破效率、施工安全及经济成本。近年来，随着智能爆破技术的发展，参数优化已从经验设计转向“理论计算-数值模拟-现场试验”的一体化模式。本文针对中深孔爆破参数设计的核心难点，结合岩体物理力学参数测试结果，重点优化孔径、孔深、孔网参数、炸药单耗等关键指标，同时提出振动控制、飞石防护等配套技术措施，为同类工程提供技术借鉴。

Abstract

As a core technology in mining, infrastructure construction, and related engineering fields, the scientific design of parameters for medium-deep hole blasting directly determines blasting efficiency, construction safety, and economic costs. In recent years, with the advancement of intelligent blasting technology, parameter optimization has shifted from empirical design to an integrated approach combining “theoretical calculation, numerical simulation, and field testing.” This paper addresses the key challenges in parameter design for medium-deep hole blasting. By integrating test results of rock mass physical and mechanical parameters, it focuses on optimizing critical indicators such as hole diameter, depth, hole network parameters, and explosive consumption. Additionally, it proposes supporting technical measures like vibration control and flying rock protection, providing technical references for similar projects.
