rock drivage

This paper analyzes on and probes into the factors influencing the speed of rock drivage such as the cyclical footage, drift forming, blasting efficiency, hole depth, and organizational management, etc.

对影响岩巷掘进速度的循环进尺、巷道成型、爆破效率、炮眼深度、组织管理等因素进行了分析探讨。

At present,in the building of new shaft,rock drivage takes 40%-50% of whole project,and the construction takes 35%-50%.

目前,在新井建设中,岩巷掘进工程量一般约占总工程量的40%~50%,施工工期占35%~50%。

The system model based on computer aided design and expert system techniques is established through analytical studying on the engineering data of rock drift tunneling.

通过对岩巷掘进工程资料的分析研究,建立了基于辅助设计和专家系统技术的系统模型。

The calculation method of reasonable delay time of millisecond blasting in rock drifting is put forward.

先行理论分析建立岩巷掘进爆破合理延迟时间的计算公式，而后模型试验研究并优化，并据此进行工业试验。
