- Abstract
An coal mine belongs to the coal mining under medium aquifer, under which there is no stable clay aquifuge.To demonstrate the safety and reliability of coal and rock pillars, study and analysis of the failure and movement feature of overlying strata are conducted in the condition of the mine’s geology and coal mining. The mechanism of mining with sand-proof pillars are revealed. The obvious economic benefits have been obtained. The reliable basis is provided for enhancing the mining limit for similar coal mines.
