基于传递岩梁理论、顶板来压经验公式预测张集矿1611(3)工作面顶板来压步距,通过对大采高工作面矿压观测,验证了顶板来压预测的准确性,分析工作面回采过程矿压显现特征及其规律,为指导大采高工作面的安全生产提供科学指导。
Based on the theory of rock mass transfer and roof pressing empirical formula, the roof pitching pressure of the 1611 (3) working face of Zhangji Mine is predicted. Based on the observation of rock pressure in the working face with large mining height, the accuracy of roof pressure prediction is verified. Surface mining process pressure characteristics and its law, to provide guidance for the safety of large mining face to provide scientific guidance.
