摘要
以某矿11030工作面作为实验研究对象,利用深部基点测量方法对开采过程中的3个测点煤层变形量进行实时测量,分析整个过程的煤层变形规律,考察卸压效果,此结论可以为后续的保护层开采研究提供实验理论帮助。
Focusing on mine 11030, measures the deformation of the protective layer by the method of deep measurement basis points, analyses the deformation rule of mining, investigates the effect of pressure relief in the mining process. The result can offer theoretical and experiment basis for the following researching the rule of protected stratum.
