摘要
大采高综放开采技术增加了割煤高度和放煤空间,大采高综放工作面的矿压显现和围岩控制必然不同于普通综放工作面。根据某大型矿井9号煤层的赋存特性,对9304大采高综放工作面进行现场观测,并分析矿压数据,研究了9304工作面矿压显现规律和支架合理工作阻力等问题。
Fully mechanized top coal caving technology raises cutting laelgnt anu cap space. The strata behaviors and surrounding rock control of the fully mechanized top coal caving are different from other average mining face. On the ground of occurrence characteristics of No.9 seam, No.9304 top coal caving face was tested. The strata behaviors and the working resistance of support are studied on the stress data.
