已研制出一套新的爆破破坏判据（或称爆破危害判断准则），重点论及深孔崩落采矿作业，综合应用振动水平、岩石性质、现场特点和地表支护系统的效应来判断破坏程度。主要目的是提供一个颇精确的数据库，用以优化爆破设计、数据分析和地表控制专家系统模型的开发。介绍的新破坏判据可采用称之为爆破破坏指数（BDI）的一个无量织参数来估量对岩石结构的破坏程度。据此可用一个统一的模式来描述爆破弓没的破坏，有助于制定数字模拟的编码，用以普遍地表述爆破破坏程度。为验证这一指数，在一座大型贱金属地下矿山对若干采场生产和掏槽爆破进行了许多现场调研。调研结果表明，观测到的破坏和根据BDI值预测到的破坏状态之间有良好的一致性。此外，为最大限度减轻大型地下矿深孔崩落采矿作业的爆破破坏，提出了一些实用措施。 A new set of criteria has been developed for blasting failure (also known as blasting hazard judgment criteria), with emphasis on deep-hole caving mining operations, the degree of damage judged by comprehensively applying the effects of vibration level, rock properties, site characteristics and surface support system . The main objective is to provide a fairly accurate database to optimize the development of expert systems models for blasting design, data analysis and surface control. The introduced new damage criterion can be used to measure the extent of damage to the rock structure using a dimensionless weave parameter called the Blast Damage Index (BDI). Accordingly, a unified model can be used to describe the failure of a burst bow, which helps to formulate digital simulation code to generally describe the extent of blast damage. To verify this index, a number of field studies were conducted on several stope production and undercutting at a large underground basement mine. The findings show that there is good agreement between observed damage and the predicted damage status based on BDI values. In addition, some practical measures are put forward to minimize the blasting damage of deep-hole caving mining operations in large-scale underground mines.
