以大量实验数据和现场测试资料为依据,研究了隐伏煤田基岩风化带岩体的分布特点及工程地质特性,重点论述了邻近风化带开采的覆岩破坏和矿山压力显现规律以及缩小防护煤柱的机理,对类似矿井的资源回收与安全开采具有重要的参考价值。
Based on a large number of experimental data and on-site test data, the distribution characteristics and engineering geological characteristics of rock mass in bedrock weathering zone of concealed coalfield are studied, and the overburden destruction and pressure show in the vicinity of weathered zone are discussed. The mechanism of similar mine resources recovery and safety of mining has important reference value.
