摘要
依据刘桥一矿II661大倾角俯仰采工作面为研究背景,通过现场矿压实测,对支架初撑力、工作阻力等进行分析,研究了大倾角俯仰采开采过程中俯采阶段及仰采阶段的矿压显现规律。研究得出的结论可为采区其他工作面煤层开采提供现实的指导意义,并可对皖北矿区具有类似煤层条件的矿井开采提供参考。
Based on parameters of the hydraulic support, such as setting load and working resistance which from the large tilt angle compound mining in II661 Work Face of Liuqiao Coal mine,the paper analyzed the laws of the mine pressure appearance of the downward mining period and the upward mining period. The conclusion of the study can offer a reference to the similar geologic mine of Liuqiao Coal mine around the areaa.
