摘要
小煤窑的无序无证开采,形成的采空区等地质异常体常因富含水或瓦斯而成为影响煤矿安全生产和建设的隐患。为解决上述问题,本文介绍了活性炭测氡法、瞬变电磁法和可控源音频大地电磁法三种勘探方法的原理、特点以及在采空区探测中的应用效果,并以太原煤气化嘉乐泉煤矿周围采空区的探测为例,证明了三种方法互补,互证,定位、定性准确,探测效果明显。
Mined-out areas and other abnormal geological areas caused by mining without license usually become the hinder danger for safety production and construction of mines because of large content in water and gas. To solve the problem, the paper introduces the theories, features and application effects of three methods： radon surveying technique with activated charcoal, TEM （transient electromagnet method）, and controlled-source audio-magnetotellurics method. The mined-out area of Jialequan Mine of Taiyuan Coal Gasification Co. is taken as an example to show that the three methods are complementary and have good exploitation effects.
