Abstract:According to the characteristics of stress field surrounding cracks and by theoretical analyses of fracture mechanics, it was found that the wallrock alteration is controlled by the microcracks developed at crack-tip. The new mode of alteration development controlled by conditions of fracture mechanics was proved by the facts that the variation in regularities of alteration zones and lode-thickness is determined by the extension-length and driving stress of crack
