摘要： 为了满足井下设备安装和运输的需求，需要对杜家沟煤业2-108 切巷进行刷扩。刷扩后，巷道断面大幅度增
大，需要重新进行支护。根据切巷的地质情况，采用了锚网索梁联合支护，并对支护参数进行了确定和校验，可以为巷
道刷扩支护提供一定的参考。

Abstract: In order to meet the needs of underground equipment installation and transportation, it is necessary to brush and
expand the 2-108 cutting roadway of Dujiagou Coal Industry Co., Ltd. After brushing and expanding, the cross-section of the
roadway significantly largens, requiring new support. Based on the geological conditions of the cutting roadway, the combined
support of anchor mesh cable and beam was adopted, and the support parameters were determined and verified, which can provide
a certain reference for the brush expansion support of the roadway.

Key words: roadway brush expansion; support; anchor mesh cable and beam
