| 摘 要： | 目前煤矿采用的沿空留巷采煤法多是留设运输平巷，由于该巷机电设备多、人员多又无轨道，给运送巷旁支护材料带来诸多不便，造成巷旁不能及时支护，留巷变形量大影响生产．为改变这种状况，提出了用小煤柱留设材料巷来解决以上问题，并对小煤柱护巷的可行性、护巷原理及有关参数进行了分析研究，它的推广使用对进一步扩大无煤柱开采的应用范围起到积极的作用．

| Abstract: | The feasibility, principle and the parameters of the roadway supporting with small coal-pillar have been analysed and studied so as to improve the roadside supporting and avoid greater deformation in the roadway. This will play an active role in using non-coal-pillar Tnining in more mines. |

| Keywords: | small coal-pillar for entry-protection gob-side entry retaining roadway-side support material roadway |
