地压控制和支护工作的好坏,直接影响到自然崩落采矿方法试验的成败。根据金山店铁矿具体的矿岩条件,采取了相应的支护措施,使采矿方法试验获得了成功,并通过现场和室内研究,基本摸清了试采过程中的地压显现特征,为自然崩落法的推广应用提供了成功的经验。 Ground pressure control and support work is good or bad, a direct impact on the success of the natural caving mining method test. According to the specific rock and iron conditions of the Jinshandi iron mine, corresponding support measures have been taken to make the mining method test successful. Through field and laboratory studies, the ground pressure characteristics in the trial mining process have been basically ascertained, The popularization and application of caving method has provided successful experience.
