一、事实教育了我们 我们地震台位于大同市西北上皇庄,在北东向口泉断裂带上。在我们台西偏南8—40公里范围内,是我国重要产煤基地之一─—大同煤矿采煤区。从1970年我们建台以来,矿区经常发生顶板塌陷,被我们微震仪记录下来。开始,由于我们是初搞地震工作,对记录图上的塌陷波形认识不了,常常错误地认为是小地震和爆破。直到1972年3月28日,在大同以西云岗公社校尉屯一带发生一次有感地震,引起国家地震局的重视,当即组织了几个单位,经过实地宏观调查后,才明确认识到,不是天然地震,而是煤矿采煤区的塌陷地震。这次塌陷给煤矿造成了危害,教育了我们。之后,大同市、矿务局的党政领导,工人同志们向我们提出希望,如何利用微震仪监视矿区的顶板塌陷,并能有效地作出予报?这样,我们在思想上提高了一步,认识到我们大同地震台,不但对天然地震要监视予报,而且对煤矿塌陷地震也要监视予报,只有把两方面监视予报工作都做好,才是真正为工农兵站好岗、放好哨、服好务。
First, the fact that we have education We are located in the seismic station Datong Huangshan Zhuang northwest, in the north-east to the mouth of the spring fracture. It is one of the important coal producing bases in our country, Datong coal mine’s coal mining area, within 8-40 km of southwest of our country. Since we built the station in 1970, the roof collapses frequently in the mining area and is recorded by our microseismometer. Initially, since we were engaged in seismic work in the first place, we did not know the collapse waveform on the record, and we often mistakenly thought it to be a small earthquake and blasting. Until March 28, 1972, a sensational earthquake occurred in Datong, west of Yuantong Commune, Datong, causing a great deal of attention by the State Seismological Bureau. Several units were immediately organized and it was only after a macro investigation on the ground that it was clearly realized that it was not Natural earthquake, but the coal mining area collapsed earthquake. This collapse caused harm to the coal mine and educated us. After that, the party and government leaders and workers’ comrades in Datong and the Mining Bureau put forward their hope to us and how to use microseismometer to monitor the roof collapse in the mining area and make an effective report. Therefore, we have stepped up our thinking and realized To our Datong Seismic Station, not only to monitor the natural earthquake to be reported, but also for coal mine collapsed earthquakes should also be monitored and reported only by monitoring and reporting are good on both sides, it is the real station for workers and peasants station, put the whistle , Good service.
