摘要： 采动影响下的回采巷道矿压显现规律研究十分重要。通过对禾草沟一矿15214 工作面进行矿压观测，研究了
回采过程中的轨道顺槽矿压显现及超前支承压力影响范围等矿压显现特征。结果表明：超前支承压力影响范围为0～30 m，
显著影响范围为0～7 m，来压峰值在煤壁前方5耀8 m 范围内；顶底板变形量稍大于两帮变形量，顶底板变形量最大为
264 mm，两帮变形量最大值为115 mm，锚杆支护明显影响范围为9耀12 m，此范围之外影响较小。研究可为禾草沟一矿
安全生产提供理论依据和实践指导。

Abstract: It is very important to study the mine pressure appearance law of mining roadways under mining influence. Based on
the observation of mine pressure in 15214 working face of Hecaogou No.1 Coal Mine, this paper studied the characteristics of
mine pressure appearance law in the mining process, such as the rail channel mine pressure appearance and the influence range
of the advance bearing pressure. The results showed that the influence range of advance bearing pressure was 0~30 m, the
significant influence range was about 0~7 m, and the peak value of incoming pressure was within 5~7 m in front of the coal wall;
the deformation of roof and floor was slightly larger than that of the two sides, the maximum deformation of roof and floor was
264 mm, the maximum deformation of the two sides was 115 mm, and the obvious influence range of bolt support was 9~12 m,
with little influence beyond this range. The research can provide theoretical basis and practical guidance for the safety production
of Hecaogou No.1 Coal Mine.
