在 Horonai 煤矿石门掘进时对岩石和瓦斯突出时伴随的声响进行了观测。在现场成功地观测了爆破之后的两次突出。在这个观测的基础上讨论了突出发生机理和预报突出的可能性。实际上,当具有突出倾向的煤层暴露于工作面时,突出前岩石的声响活动在爆破之后明显增高。从而证实了:在爆破之后,监测声响活动增加的幅度就很可能对即将发生的突出做出预报。而且,这个观测结果也对发生突出的过程给予了新的解释。
The sound accompanying the rock and gas outbursts was observed during the Horonai coal mine tunneling. In the field successfully observed after the blast twice highlighted. Based on this observation, the possibility of highlighting the mechanism of occurrence and highlighting the forecast is discussed. In fact, when the predominantly inclined coal seam is exposed to the work surface, the acoustical activity of the protruding fore rock is significantly increased after the blasting. Confirming that, after blasting, it is very likely that the magnitude of the increase in monitoring sound activity will predict the impending outburst. Moreover, this observation also gives a new explanation for the processes that are prominent.
