| 摘 要： | 针对京煤集团木城润矿大台井地质条件与煤的赋存状况，通过相似模拟实验和数值模拟方法，讨论急倾斜煤层开采解放层的可行性。通过观测相似模拟实验中的煤岩失稳过程，定性地了解冲击地压的发生规律，裂隙带发生、发展过程和解放范围。采用反映煤岩等脆性材料破坏特征的五参数Wilianm-Warnke强度准则破坏模型，利用有限单元法单元“处死”的功能真实模拟开挖过程，进行急倾斜煤层开采解放层防治冲击地压的数值模拟研究，作为定量分析依据。为急倾斜煤层开采解放层防治冲击地压制定较为合理的方案、安全技术措施等提供重要的科学依据和理论指导作用。

| Abstract: | In view of the geological conditions and the located situations of coal in Datai, Muchengjian mine Beijing, the possibility of extracting liberated seam is discussed in dip-slopping coal seam through simulating experiment. The rule of rock-burst, the generation and development of crack band, and the range of liberation are learned through observing the process of failure. Willianm-Warnke strength failure criterion is adopted; the function of element is killed dead in finite element method to simulate mining process. It can provide an important scientific foundation and theoretical guide to formulate reasonable plan and safe measure for dip-slopping coal seam mining liberated seam for preventing rockburst. |
