运用钻孔封堵技术进行岩层破坏范围探测是一项简单方便、行之有效的现场测试方法 ,已经成功地进行了数十个矿井的顶板覆岩破坏“两带”高度的探测研究 ,为矿井提高开采上限 ,留设安全煤岩柱提供了可靠的数据资料 ,但这些工作均是在仰斜钻孔中完成的 ,在俯孔中进行岩层破坏范围探测研究还不多见 ,文章对俯孔中的观测方法、数据处理以及测试中的几个问题进行探讨。 Using borehole plugging technology to detect rock failure range is a simple, convenient and effective field test method. We have successfully conducted the exploration research on the “two-zone” height of overburden rock failure in dozens of mines, Increasing the upper mining limit and leaving safe coal and rock pillars provide reliable data. However, all of these works are done in the borehole. In the hole-punching, the research on the detection range of rock failure range is still rare, In the observation methods, data processing and testing of several issues to be explored.
