泉州市部分石材矿山地质灾害调查分析

On Diagnoses of Geologic Hazards in Some Stone Mining Areas of Quanzhou City

针对泉州市4个主要石材采矿带的矿山分布特征及矿山开采状况进行调查分析,认为各矿山采矿场地普遍偏小,以个体开采经营为主,机械化程度低,开采作业较零乱,开采边坡大多数形成高陡的采掘面,缺少安全台阶。各矿山综合治理相对滞后,废石、废碴随意堆放,均存在不同程度安全隐患和潜在的地质灾害,通过分析研究,提出预防建议和对策。

Based on the investigation and analyzing of mining production and distribution characteristics for the four main stone mining regions in Quanzhou City, it is shown that the diggings of stone mining areas in the surveyed area are smaller in scale and lower degree of mechanization and that the mining production is in disorder comparatively and the great majority of mined highwalls form into cliffy working faces lacking in safe sidesteps. Because of low-level comprehensive treatment for the stone diggings and random stockpiling of waste rocks and residues, a variable degree of potential safety hazard and potential geologic hazard come into existence in the surveyed area. Finally, the paper presents some countermeasures and proposals of protection against the potential safety hazard and potential geologic hazard.
