摘要
大采高综放开采技术是特厚煤层开采的新途径,它结合了大采高与放顶煤的特点;但在矿压显现规律上又不同于两者。文章根据神东保德煤矿8#煤层的赋存特性,对大采高综放工作面81300-2进行了矿压观测,并对采场的矿压规律及支架合理工作阻力等问题进行了研究。
Large-mining-height fully-mechanized mining technology is new for mining extra-thick seam,which combines features of the large-mining-height mining and caving,but the strata behavior is different from those two.The article is based on the existing characteristics of No.8 seam in Baode mine,ground pressure observation on the 81300-2 working face was carried out.The strata behavior and supporting reasonable resistance are studied.
