According to simulated results , we can get the range of side pressure relief at the mining face , at the upper coal or the lower coal under the peculiar condition 根据模拟结果得出：特定开采条件下，上部或下部不同煤层采煤工作面侧向却压区范围。
Aimed at the shortcomings of coalface passing through fault as low speed , low efficiency and low - quality coal and so on , a new technique was suggested 摘要针对采煤工作面过断层速度慢、效率低且影响煤质等缺点，提出工作面快速无矸石过断层清洁开采技术。
