摘要:

为了对某矿区近地表开采可能出现的地质灾害进行评估,采用离散元数值模拟方法,研究了近地表开采不断深入可能造成的地表扰动和地质灾害。结果表明:在开采过程中应采取切顶、护顶、留点柱等方法控制顶板冒落,且随着矿体倾角的增大,顶板冒落范围也将随之增大。开采过程中应注意矿体倾角的变化,加强顶板管理。研究为后续矿山选择合理的采矿方案提供了一定的理论依据。

Abstract:

In order to evaluate the potential geological disasters of near-surface mining in a mining area,the potential surface disturbance and geological disasters caused by the deepening of near-surface mining were studied by using the discrete element numerical simulation method.The results show that in the process of mining,roof cutting and pillar retaining methods should be adopted to control roof caving,and with the increase of the dip angle of the ore body,the roof caving range will also increase.Therefore,the change of the dip angle of the ore body should be paid attention to and the roof management should be strengthened.The research provides a certain theoretical basis for the mine to subsequently choose a reasonable mining scheme.
