摘要
薄煤层工作面由于采高过低,在回采过程中遇到断层工作空间较小,过断层选择的方法是否合理直接影响薄煤层开采的整体经济效益。以1201薄煤层工作面为例,介绍了工作面过不同种类断层采取的方法和辅助措施,同时在过断层时要选择合理的支护方法。1201薄煤层过断层实践表明,这些方法和措施效果明显,能够提高工作面煤炭回采的整体经济效益。
Because of the low mining height at thin--seam working face and small workspace of fault in the mining process,the way of crossing fault has a direct influence on the whole economic benefit in mining thin coal seam. The paper introduces the ways and assistant measures of crossing different faults as well as the rational selection of support methods, which can increase the whole economic benefit of coal mining,
