摘要
针对仙泉煤业4304大采高综采工作面进入泮沟南向斜构造影响区后支架出现不同程度的倒架现象,采用理论分析和工程类比的方法,提出了大采高综采面过构造影响区时防治倒架的"掏槽掘进预先支护顶板"法,现场应用效果良好。"掏槽掘进预先支护顶板"法在4304大采高综采工作面支架防倒中的成功应用,对指导类似条件大采高综采工作面的生产具有重要意义。
For the support tilt phenomenon in varying degrees when height long wall with large mining coal working face No 4304 was in Pangounan syncline area, the theoretical and engineering analogy methods were used. And the method of the cutting excavating and supporting the roof in advance was proposed, it is proofed fine in field application. The successful application of the method in anti-tilt of supports in height long wall with large mining coal working face No 4304 had great significance for guiding similar conditions.
