摘要
在DKJ-1型煤矿矿压计算机监测系统工业性试验的基础上,以7次顶板运动过程中监测到的地音参量、顶底板移近速度和来压实况为依据,分析了地音、位移前兆与顶板来压的关系。
The relation between the geoacoustic and displacement omens and roof weighting was analysed on the basisof the geoacoustic perameters, convergence speed and ac-tual weighting behavior, which were monitored and mea-sured during the industrial test of the computor-aided un-derground pressure monitoring system type DKJ-1. Theresults show that the saltation of event frequency is theimportant information of the breakage of the hangingroof shelf, or the geoacoustic omen of roof weighting. A-gain, it appears slightly earlier than the displacementomen. Geoacoustic monitoring will be an effective meansof realizing the monitoring on surface and prediction ofthe stability condition of surrounding rock and roofweighting.
