1·Therefore the analysis is about the characteristic of gob combustibility gas, to suppresses the gas explosion, prevented the disaster the occurrence has the vital significance.
所以分析采空区可燃性气体爆炸特性,对抑制瓦斯的爆炸、防止灾害的发生具有重要意义。
2·According to the calculation results, the writers arrive at the conclusion that the larger gob and larger horizontal tectonic stress are the important causes to induce the floor heave, etc.
基于计算结果,本文发现较大的采空区范围以及较大的水平地质构造应力是导致该区域巷道底鼓的重要原因等结论。
3·The reasonable layer selection is the main influencing factors for gas drainage by high level borehole, the borehole parameters is based on the caving & fracture zone height of gob.
高位钻孔抽放最主要的影响因素是合理层位选择,其钻孔参数应根据采空区冒落带及裂隙带高度来设计。
4·Underground and ground transfer system of gas, pipeline layout and underground gob distribution have briefly been introduced.
简要介绍了瓦斯在井下和地面运输中的输配系统、管道敷设以及井下采空区分布状况。
5·The other is used for the falling and collapsing of gob.
另一是由于采空区的崩落和塌陷。
