【摘要】 石材水压的断裂与炸药的爆破作用机理有所不同。本文论述了石材在静载作用下的力学特性，建立了石材在水压作用下断裂计算的力学模型，分析了断裂控制的基本原理，给出了石材水压涨裂系统的主要设计参数及其在矿山上的实际应用。更多还原

【Abstract】 The rnechanismof hydro-expansion cracking is different from of explosive blasting for stonematerirals. This paper describes the rnechanical properties of stone-materials under static load; sets up themechanical models for calculating hydro-expansion cracking of stone-materials; analyses the principle ofcracking control; gives main design parameters of hydro-expansion cracking system and their using inmines.更多还原
