摘要: 对典型构造地裂缝的空间分布、活动特征、成因机制等方面进行了论述,认为构造地裂缝的内因是地质断裂,外因是地下资源过量开采;在勘探构造地裂缝中,只要观测系统设计合理,参数选择准确,资料处理得当,地震勘探可以准确地给出地裂缝从十几m到几百m深度内的各项地质构造参数及在地表的位置,满足科研和工程的要求。

Abstract: The space distributions,activities,causes and mechanisms of the tectonic ground fissures are discussed.It is believed that the geological faults is the internal cause of the ground fissure hazard and the over-withdraw underground resources is the external cause. For the tectonic ground fissures probing,the seismic exploration is practicable with suitable survey system, appropriate parameters and right data processing, and it may successfully give the tectonic parameters of the ground fissures in the profile from dozen to several hundred meters depth and the their locations on the ground surface.
