摘要
随着开采深度的增加,不同采煤工艺下的矿压显现问题的研究越来越重要。本文简单介绍了开滦赵各庄矿深部地应力的实测原理与技术、测试方法和测量结果,对矿井深部地应力特征进行了分析,为今后工程设计、层位选择、支护方式等多方面的工作提供参考。
With mining depth increasing, the study on ground pressure appearing is getting very important. The paper briefly introdues the testing theory, testing technology, testing method and results of stress measurement in deep area in coal mine, and makes an analysis of the stress characteristics in deep area, which can be referred to the future engineering design,layer choice, supporting and so on.
