摘要
通过对陕北神府矿区浅埋煤层强制放顶工作面矿压显现规律的模拟研究表明,合理的强制放顶措施有助于降低工作面来压显现程度,并削除岩层沿煤壁切落的顶板事故发生,为现场采用悬移支架等轻型支架创造了必要条件。
The strata behavior laws of shallow coal seam mining face by using forced caving in Shenfu mining area of northern Shaanxi were researched. The results show that reasonable forced caving measures can reduce the degree of strata behavior and avoid the roof cutting accident in mining face. The research provides the necessary condition for the use of light hydraulic supports in Shenfu mining area.
