| Abstract: | The paper has studied the strata distributive character and engineering geologic property of bed rock zone of weathering in cryptical coal field, based on large of data form testing and real-field materials, taking importance on the laws of overlying destruction and underground pressure behavior and the mechanism of decreasing protective coal columns while extracting proximity zone of weathering. It has important reference value to recover coal safely in similar coal mine. |
