Field investigations and laboratory testing, along with a three¬dimensional numerical model study for 18 underground coal mine running panels, was done to compile the findings in this paper. A total of 612 three-dimensional numerical models were run with different combinations of geotechnical parameters obtained from field investigations and laboratory testing [2]. It was found that the following are the most common causative factors associated with support load at depillaring faces.
RMR and strength: The RMR and strength (O"e) values of the immediate roof of each mine were varied by 10-25% hypotheti¬cally to get sufficient range. Although a ; is included in RMR it was varied independently for generality.
Depth of cover: Based on modelling it is observed that depth of cover is an important parameter. The 18 field cases used for modelling have depth of cover between 27 and 265 m.
Horizontal in situ stress: Three hypothetical values for horizontal in situ stress [13-15] are taken as follows:

现场调查和实验室检测以及一个三维煤矿井下18运行的数学模型研究小组,是为了编译本文的结果.一个612三维数值模型共运行从野外调查和实验室检测[2]获得岩土参数的不同组合.结果发现,以下是一些相关的支持负载在depillaring面临的最常见的致病因素.RMR和强度：RMR和力量（海外的“e）每个矿井的价值是多方面的直接顶了10-25％,假设得到足够的射程.虽然,包括在不同的RMR是对公众独立,深度包括：建模据观察,深度覆盖是一个重要的参数为基础.在18场建模使用的情况下有保护层厚度在27和265米.包括在不同的RMR是对公众独立.水平地应力：三种假设的水平地应力值[13-15]采取如下：
