矿山冲击的地震学研究与开发

国家地震局地球物理研究所与中国统煤总公司北京矿务局合作,将地震学的成熟方法引入对矿山冲击的研究。在监测系统改造、分析软件包编制、震源机理研究、矿山冲击分类和冲击预测专家系统研制等方面,都取得一定进展,并展示出极广阔的应用开发前景。本文则是这些工作的综合性总结。

The Seismological Research and Development on Mining Tremors

A sophisticated seismological method has been introduced to the study of mining tremors by the Institute of Geophysics of SSB in cooperating with the Bejing Mining Bureau of NCC. We have obtained some achivments in the following aspects:-The special facility,SAK-SYLOK, imported from Poland has been modified into a new system which include some standardized outer device and so on controlled by a general personal computer.-A software package for analysis of mining tremors (SPAMM) has been compiled and applied in real condition.-It was preliminarily found that the mechanical model for mining tremors is generally made up of both sharing and expanding by the program for calculating wave filed.-A table of classification and grade of mining tremors was made,based on induction of data of in-situ,ground pressure measurement,record tremors and geosound.-Expect system of mining tremors prediction is being developed by referring to some schemes of seismological institution, the theories and experiences of mining engineers, geophysists and expert on rock mechanics.
