开滦东欢坨矿北二采区冒裂带高度可视化数值模拟

Visual numeric simulation of the height of fractured zone in No.2 northern working area in Donghuantuo Mine,Kailuan

摘要: 针对东欢坨矿区开采煤8、煤9诱发的顶板涌(突)水问题,在分析研究区内水文地质、工程地质条件的基础上,综合考虑了冒裂带发育高度的各种影响因素,确立了研究区的评价模型,并根据采面规格和开采方法设计了6种模拟方案。采用世界上先进的数值模拟评价的FLAC^3D专业软件包,对开采煤8、煤9顶板冒裂带发育高度进行了可视化数值仿真模拟分析,计算出6种方案的冒裂带高度。

Abstract: According to the water burst problem induced by exploitation of coal 8 and coal 9 in Donghuantuo mine,the hydrogelogical and engineering geological conditions are analyzed in detail.Based on comprehensively considering the effected factors of break height,the assessment model is established,and 6 types of simulated projects are designed.Using advanced software package of FLAC^3D,a visual numeric simulation is conducted in analysis of break height of coal 9.
