摘要
近年来,地面磁法仪器测量精度和读数速度有根本性改变.特别是Overhauser和铯光汞磁力仪的应用,使读数间隔达0.1 s,而带有载波相位的GPS实时定位精度可达分米级.据新疆西天山尼勒克县群吉萨依铜矿区应用实例,展示出地面磁法连续测量比常规点距能够获得更多地磁场信息,提高发现异常能力和定性、定量解释精度.因此,该方法具很高社会效益和实际应用价值.
Recently, the ground magnetic measuring precision and reading speed get a high improve. For the use of cesium optical-pumping magnetometer and Overhauser magnetometer, makes the readings interval can achieve 0.1 seconds. With a Carder phase GPS, the Real-time positioning precision reaches 10-1m. It makes the ground magnetic measuring to be Near-Continuous. Based on the test of Qunjisayi copper mine in the West Tianshan, this paper shows that the near-continuous method gets more information of geomagnetic field. And it gets more abilities of finding abnormal and higher precision of the interpretation. With high social benefits and actual application value, it is good for generalization.
