分析了硐室爆破设计过程中存在的一些问题，阐述了硐室爆破自动设计系统的开发途径、基于理论计算法的炸药单耗的计算机选取以及安全因素的合理预测。对药包形态、微差时间、导硐堵塞也作了描述。

The paper analyses some problems in the chamber blasting design and expounds the development approach of the automatic chamber blasting design system, computeraided selection of the specific charge based on theoretical computation method and the reasonable forecast of the safety factors. Furthermore, the paper also describes the charge shapes, the differential time and the guide hole stemming.
