| 摘 要： | 回采巷道所选用的护巷方式及支护形式直接决定了回采工作面开采的难易。本文通过对不同护巷条件的几条综采工作面回采巷道的矿压显现观洲，介绍了木支护、金属棚支护的试验情况及矿压显现特点，分析了沿空掘巷(留小煤柱)合理支护方式，提出了沿空掘巷布王的合理小煤柱尺寸及支护方案。

| Abstract: | The difficulties of mining in working faces are directly decided by support patterns in gateways. This paper introduces the testing situation of timber support and steel support and roof behavior characteristics, analyzes the reasonable support mode of gob-side entry driving(with small coal pillars), and puts foraward the reasonable dimensions of small coal pillar and support plan by observing roof behavior characteristics of gateways with different supporting conditions in several fully-mechanized working faces. |
