煤矿井下直流层测深方法与原理

DC LAYER SOUNDING IN COAL SEAMS

煤层小构造的采前探测是煤矿生产中的薄弱环节。煤矿井下直流层测深方法在探测煤层小构造及对其含水性进行评价方面独具特色，在淮北矿区的初步应用中已显示了该方法的优越性。文中主要阐述了直流层测深法的工作原理、井下施工方法与技术、理论曲线的正演模拟，以及资料解释的一般原则，并提供了应用实例。

Detection of microstructures in coal seams prior to mining is a vuinerable link of coal production. This paper presents the method of DC layer sounding which is specially used for detection of microstructures in seams and for evaluation of water-bearing strata. The advantages of this method are clearly deinonstrated in Initial application in Huaibei area. In this paper, the working principle, operation, technique of this method are given, and forward analogy of the theory curves and the basic principle of data interpretation, as well as an applying case,are described.
