宁夏大峰矿5500t爆破及观测研究

2007年底在宁夏和内蒙古交界的贺兰山大峰煤矿进行了5500t的大当量工业爆破，这是一次进行地球物理、工程抗震等研究的难得机会，同时也是全面检测宁夏及邻区“十五”新建测震及前兆系统运行情况及工作状况的机会。除了加强固定测震台网的监测外，宁夏回族自治区地震局还联合甘肃，四川，青海4省地震局布设了南北向的临时测线。北京大学，中国地震局地球物理勘探中心及爆破单位等十余家单位，分别在不同地点沿不同方向布置了不同研究目的的测线。本文就此次爆破和观测情况做简要介绍。

Introduction of 5 500 tons blasting in Dafeng mine, Ningxia as well as its observation and research

At the end of 2007, it had one industrial blasting at the equivalent of 5 500 t at Dafeng mine, Helan Mountain in the junction of Ningxia and Inner Mongolia. It is a rare opportunity to study geophysics and earthquake resistant engineering. It is also an opportunity to a comprehensive test on operation situation and working condition of seismometry and precursor system newly built during the 10th plan in Ningxia and its adjacent areas. In addition to strengthening seismic monitoring of fixed network, Earthquake Administration of Ningxia Hui Autonomous Region, combined with other three Earthquake Administration of Gansu Province, Sichuan Province and Qinghai Province, laid temporary North-South survey line. More than 10 units also separately laid survey line at different locations along different directions for different purpose of study, such as Peking University, the Research Center of Exploration Geophysics, China Earthquake Administration and blasting unit and so on. In the paper, it is the purpose to make a brief introduction of the blasting and its observation.
