| 摘 要： | 华北地区下组煤资源丰富,却深受奥灰水困扰,有必要进行煤层底板突水评价及矿井涌水量预测。文章首先简要介绍了常见的底板突水评价及矿井涌水量预测方法,指出了各自的优缺点及适用条件。之后以显德汪矿9#煤层为例开展案例研究,研究结果表明：矿区中南部可划为底板突水危险区;若将突水危险区-200m水平奥灰水压降至安全水压,预测涌水量为2 000m3/h;目前实际开采9#煤突水过渡区,在使用必要的注浆措施后,发现回采是安全可行的。本研究在提升煤炭资源保障能力、延长矿山开采年限和加强煤炭安全生产方面具有理论与实践意义。

| Abstract: | Resources of the lower group coals in the North China coalfields are abundant,but seriously perplexed by Ordovician limestone water,thus to carry out coal floor water bursting assessment and mine water inflow prediction are necessary.The paper has introduced common floor water bursting assessment and mine inflow prediction methods at first,and pointed out respective merits,demerits and applicable conditions.Afterwards,carried out case study of No.9 coal seam in the Xiandewan coalmine,the results have demons... |
