1) bore water bursting
钻孔突水
2) drilling for outburst control
防突钻孔
1.
In order to get a better understanding of sticking and spraying orifice in the process of drilling,taking operation drilling for outburst control for example,the mechanical model for borehole instability of drilling is established based on theoretical analysis.
为了进一步认清在钻孔施工过程中经常出现卡钻、喷孔等问题,本文以掘进面施工防突钻孔为例,以理论分析为主要手段,建立了钻孔失稳的力学模型,分别研究了钻孔孔底和孔壁附近煤体的破坏形式和失稳特征,并结合钻孔喷孔应具有两个基本条件:①封存的能量源;②封存障碍突然失稳破坏,而使能量源瞬间释放,得出如下结论:卸压区易发生垮孔;峰后应力集中区易垮孔也易发生喷孔;而峰值强度前区域发生喷孔的概率则大大降低。
3) drainage borehole
排水钻孔
1.
A drainage borehole designed depth is 584.
永城矿区某矿排水钻孔设计孔深584。
4) hydrological borehole
水文钻孔
1.
This paper discusses the utilization of the mine transient electromagnetic method to detect the location of hydrological borehole that lies in the coal layer or in front of the laneway,and gives a qualitative appraisal of its hydrous characteristics.
探讨了用矿井瞬变电磁法探测采煤工作面内部和掘进巷道前方的水文钻孔的位置,对其富水性进行了定性评价,总结出水文钻孔在视电阻率断面图上的响应特征,即在顺煤层方向呈圆形异常反映,而在煤层顶、底板方向呈狭长椭圆形特征。
5) moving water in the borehole
钻孔流水
6) draining water in the drill hole
钻孔淋水
1.
Influence analysis of the anchor-hold of the resin bolt by the draining water in the drill hole;
