深部大倾角综放工作面上覆煤岩裂隙演化规律研究

Cracking Development Variation Law of Overlying Strata Over fully-mechanized Coal Caving Mining Face during Exploitation Process

文章以具有"深部大倾角"特性的开滦赵各庄矿为研究对象,在现场调研和实测的基础上,通过理论分析并应用ANSYS有限元软件对其进行计算机模拟和分析,得出了在采动影响下裂隙场的发展演化的一些规律,研究结果可以为瓦斯抽放和煤矿安全生产提供一定的理论基础和指导。

Zhaogezhuang mine of the Kailuan group is chosen as the study object with the characteristic of “steeply dipping seams”. Based on actual data collected and measured in Zhaogezhuang mine, some of the cracking development variation law of overlying strata during exploitation process is gained through numerical simulation based on ANSYS, and the results also provide some of the theoretical basis and guidance for gas extraction technology and mine safety.
