可用方法的技术简介 (a) 岩石移动的监测是为了解岩体性状和评价岩体稳定性而提供的。对岩石表面裂隙的观察,可以提供有关深部岩体性状的有用资料,而且表面监测通常要比钻孔测试手段或其它地下监测技术便宜得多。 (b) 将木楔打进开裂处观察木楔在何时松动,是采矿人员常用的一种传统方法, Technical Briefs on Available Approaches (a) Monitoring of rock movements is provided to understand the nature of the rock mass and evaluate the stability of the rock mass. Observation of rock surface fissures can provide useful data on the character of deep rock mass, and surface monitoring is usually much cheaper than borehole testing or other subsurface monitoring techniques. (b) Breaking the wedge into the cleft See when the wedge is loosened, a common method commonly used by miners,
