摘要
煤矿透水是危害煤矿安全生产的主要因素之一。地面核磁共振是目前找水行之有效的方法之一。该文以神木县河西联办煤矿核磁共振找水为例,介绍了地面核磁共振数据采集、数据处理、资料解释的方法技术。通过实例表明,地面核磁共振不仅查明了该煤矿第四系内松散砂层水分布及基岩风化带水分布,而且还初步确定了埋藏深度、厚度,分析评价了富水性,圈定了不同等级的范围。
The coal mine flooding is one of the main factors that endanger the safety of coal mine production. The surface nuclear magnetic resonance is one of the effective way to find out water. In this paper,taking Finding out water in Shenmu county Hexi liaison office coal mine for example,the method and technology of data collection,data processing and data interpretation of surface nuclear magnetic resonance are introduced. The example shows the nuclear magnetic resonance not only detects the distribution of water in Quaternary system loose sand layer and bedrock weathering zone in this coal mine,but it also determines the buried depth and thickness of water,and it analyses and evaluates the watery,and it delineates the scope of different grades.
