摘要:
在矿山开采过程中,破碎带、软弱夹层等地质构造以及隐患空区的存在严重影响矿山的生产安全。开采前对工作面前方的地质条件进行超前预报,并及时采取有效的应对措施,对于矿山安全、经济且高效开采具有重要意义。为了探明某金铜矿深部矿房塌陷后涉及多中段的复杂空区位置和形状,在现场勘查的基础上,采用TRT6000系统分多中段多测点对需探测区域进行了不同方位的探测,结合钻探结果对预报结果进行详细分析与验证,并建立了反映空区形态的三维模型。结果显示TRT6000系统预报结果与钻探结果基本吻合,表明应用TRT在矿山井下开展超前预报具有可行性。建立的三维模型更加直观地揭示了空区及破碎带等问题区域可能出露的位置,为TRT结果解译的可视化提供了参考。
