轻放工作面坚硬顶板初次放顶矿压研究

Study on Mine Pressure of First Overhead Caving in Hard Roofing

摘要:

针对柴里煤矿374①综放工作面坚硬顶板初次放顶难的问题,采取了强制放顶措施,同时进行矿压观测,了解初次放顶过程中矿压显现规律,采取有效安全措施,减少初次放顶带来的危害。

Abstract:

Pointing to difficulties met in first overhead caving in hard roofing in 374① working plane,countermeasures under coercion are carried out,and mine pressure is monitored at the same time.Pressure rule showed in first caving is studied in this paper,thus,damages which will happen in first caving can be decreased.
