摘要
快速准确掌握支承压力分布规律对矿山开采设计具有重要意义。通过理论分析建立了不同运动状态工作面静态支承压力估算模型,在此基础上,利用C#开发了支承压力估算软件,介绍了软件的结构与使用方法。以山东某矿1300工作面为例,通过该软件对1300工作面侧向静态支承压力进行估算,现场动力显现与计算结果相符,表明该软件能够有效估算深部工作面支承压力分布规律。
How to accurately and quickly grasp the distribution law of abutment pressure is of great significance for mining design. Based on the theoretical analysis, the static abutment pressure estimation models of working face in different motion states were established. The software of abutment pressure estimation was developed by C#, and the structure and application method of the software were introduced. Taking 1300 working face of a mine in Shandong as an example, the lateral static abutment pressure of 1300 working face was estimated by the software. The field dynamic behavior was consistent with the calculation results, indicating that the software can effectively and conveniently estimate the distribution law of abutment pressure in deep working face.
