导水裂隙带高度研究方法概述

A brief review of the methods determining the height of permeable fracture zone

导水裂隙带高度的确定是水下采煤工作之重点,目前并没有一个完全可以精确确定的方法,主要的研究方法有经验公式法、物理模拟、数值模拟和现场实测。单靠其中的一种也不能确定,将几种方法相互结合则是准确得到导水裂隙带高度计算方法的重要途径。

Determining the height of a permeable fracture zone is an emphasis of mining under water bodies. Until recently, there are no precise methods and experiential formulas, physical simulation, numerical simulation and field measurement are the main methods. Only one of these methods cannot be used to determine the height of the permeable fracture zone. An important approach to gain exact calculation results is a combination usage of these methods.
