摘要
针对屯兰煤矿12501工作面大断面回采巷道支护困难的问题,通过现场钻孔取芯、实验室实验,得出了工作面运输巷围岩的强度特征以及结构成熟度和成分成熟度。确定了巷道支护方案与相关支护参数,并对其现场支护效果进行了分析。
Aiming at the Tunlan coal mine 12501 working face of large section roadway supporting problem, through on-site coring and laboratory experiments, get the headentry rock strength characteristics, structural and compositional maturity. The roadway support scheme and relevant support parameters are determined, and the field support effect is analyzed.
