技术简介

该技术适用于有足够厚度的急倾斜矿体和缓倾斜矿体，特别对开采厚大、低品位矿体具有较大的优势。上个世纪六十年代以前，自然崩落法主要用于开采松软破碎不稳固的矿体，随着岩石力学的发展和水压致裂矿岩预处理技术的应用，目前已经在硬岩稳固的矿山成功应用。

Introduction

This technology is suitable for sharply inclined and gently inclined ore bodies with sufficient thickness, and isparticularly advantageous for mining thick, low-grade ore bodies. Prior to the 1960s, the natural caving methodwas mainly used to mine soft, fractured and unstable ore bodies, With the development of rock mechanics andthe application of hydraulic rock pretreatment technology, this method has been successfully applied in hardrock solid mines.
