摘要
介绍了祁东煤矿在煤层厚度变化大等复杂条件下的掘进工作面应用分台阶掘进法施工及支护情况,包括应用背景、支护参数确定、分台阶掘进法简介、施工工艺及实验手段、分台阶掘进法使用后对工程质量采取的措施、分台阶掘进法使用前后比较、应用比较,应用效果等。
The paper introduces the construction and support situation of the substep drivage method at the drivage face under the big thickness change etc. complex condition. It includes: the application background, the determination of support parameters, the synopsis of substep drivage method, the construction craft and experimental method, the adopting measures to the project quality after using the substep drivage method, the frond and back application of the supstep drivage method, the useful effect etc.
