中文摘要：

针对浅埋近距离煤层工作面在推出上覆一侧采空煤柱过程中普遍出现的压架现象,以神东矿区石圪台煤矿1-2煤一盘区4个工作面的开采实例为背景,就一侧采空煤柱下切眼位置对压架发生的影响规律进行研究,由此提出避免出一侧采空煤柱压架的切眼位置确定方法。结果表明：随着一侧采空煤柱下切眼位置逐渐远离煤柱边界,煤柱上方关键层在工作面推出煤柱时的破断形态将随之改变,即由无法破断转变为大跨度悬臂式破断再转变为先初次破断后周期破断,最终影响到压架的发生及其强度。若在近距离煤层间存在关键层时,则煤柱上方关键层的破断形态还将受到该关键层破断与否及其破断形态的影响。由此针对煤层间是否存在关键层,按照切眼布置位置的不同将工作面出一侧采空煤柱的开采划分为2类7种。据此提出保证煤柱上方关键层不发生破断或其破断块体的回转对支架不产生影响的切眼位置确定方法,为压架灾害的防治提供参考和依据。

英文摘要：

The crushing of supporting structures frequently occurs in the mining out coal pillar at the side of the upper goal and in close distance to the working front of the shallow seams. The influence of the positions of hole-cut beneath the coal pillar was studied based on the mining practices at 4 working faces in Shigetai coal mine, Shendong mine area, China. A method of determining the cut-hole position was proposed to avoid thesupport crushing. As the positions of cut-hole are getting farther away from the edge of the coal pillar, the mode of the key stratum（KS） above the coal pillar varies in pushing out the coal pillar. The key stratum is stable initially, then starts to break like the cantilever. The periodic breaking occurred after the initial breaking leads to finally the occurrence of support crushing. Besides, if there is a KS in seams in close distance, this KS will affect the mode of breaking of the KS above the coal pillar. Total of 7 types in two categories of cut-hole positions were derived. The positions of cut-hole were proposed to ensure that the KS above the coal pillar would not break or its breakage would not cause the failure of supports.
