摘　　要：根据岩石破碎机理和爆破实践经验，探讨和分析了硐室爆破易产生大块的原因，提出了相应的控制措施并列举实例加以验证。这些具体做法对拓宽硐室爆破的应用范围有着重要的现实意义。According to rock blasting mechanism and practical experiences in blasting,the author discussde and analyzed the eauses producing larger rock in chamber blasting,proposed corresponding control measures and provided the examples for demonstration. This doing is of great importance to widening the use of chamber blasting.
