地层结构的应力分区与煤瓦斯突出预测分析

DIVISION OF TECTONIC STRESS ZONES AND PREDICTION OF COAL AND GAS BURSTS

地壳内的各种地质构造现象、地震、矿井动力现象都与岩体应力作用密切相关。要提高预测这些地质构造和动力现象的准确性 ,从根本上说取决于对构造应力场的研究水平。文中用 ANSYS软件结构静力分析方法 ,对岩体应力作了分析研究 ,划分了构造应力区。它对于采矿工程稳定性评价、矿井动力现象预测预防等方面都有重要意义。

The geological structure, earthquake, and mine induced dynamic phenomenon have close relation with the state of rock mass stress. In order to improve the accuracy of predicting geological structure and dynamic phenomenon, the tectonic stress must be researched. The rock mass stress and tectonic stress zones are analyzed with ANSYS Program. The analysis result is important to evaluate the mine engineering stability and to predict the mine induced dynamic phenomenon.
