本文讨论了主要开拓巷道的概念和开拓方法的分类，以及各种开拓方法在黄金矿山的应用。

This paper discusses the concept of main development tunnels and the classifications of development methods and describes the application of all kinds of development methods in gold mines .

作者通过从开采安全和经济技术方面深入研究分析，得出在1120水平白云岩中掘进巷道优于在底板页岩中布置，确定将1120m水平的开拓巷道位置变更至上盘白云岩中。

It is better for excavating the development opening at the hanging wall than at the footwall in the Level 1120 m based on the safety analysis and economic technical comparisons .

通过理论分析及实践验证，作者提出将原来的在底板中的开拓巷道改到顶板中是切实可行的；在白云岩中采用双楔形掏槽眼布置方式，能取得良好的爆破效果。

The results of studies show that it is feasible that the development opening was excavated at the foot wall , and a well blasting effect can been achieved by using the double wedge cut .

结合柳湾煤矿开拓巷道，顺槽和综采工作面切割巷，采用锚网支护试验对金属网的作用机理进行重点研究。

Combined with the experiences of developing roads , direct cuts and the cutting roads of comprehensively mining work face , the author made researches on the acting mechanism of metal net by adopting bolt net support test .

矿井开拓时期的巷道掘进，是每一个深热矿井都会遇到的最困难的排热通风问题。

The ventilation problem of the roadway excavation during the mining development is the most difficult one of all the problems about the ventilation and the exhaust heat faced with by every deep heat mine .

在地下不同的水平，开拓有许多水平巷道以通向矿脉并随矿脉延伸。这种巷道叫作平巷；

At different levels beneath the ground horizontal tunnels are excavated in order to reach and follow the vein . These tunnels are called drifts ;

多年来，由于金川岩体条件较差，地应力大，严重制约井下主要开拓、采准巷道的掘进速度，直接影响矿山生产有条不紊的进行。

For many years , because of the bad rock condition and big ground stress , it limited the main opening and the speed of drift driving seriously , directly affect the mining methodically .
