摘要:
中国某磷块岩矿床地下开采过程中,采场顶板及巷道有明显的岩爆现象发生. 通过现场岩爆的实地调查,了解现场岩爆的发生频度及发生规律,在岩爆区域现场采样进行室内微观实验分析,发现磷块岩宏观力学行为很大程度上符合其微观结构构造和矿物组成的微观力学行为,微观裂纹试验发现磷块岩晶界弱面为白云石与胶磷矿之间的接触晶界. 现场研究发现,岩爆多发生在爆破后环境干燥的区域,且多发矿段为白云石含量较高的岩层. 提出了岩爆的产生判据,并给出了岩爆的防治对策.
Abstract:
Remarkable rock burst occurred in the roof and roadway of a stope during underground mining phosphate rock deposits in China. The occurrence frequency and regularity of rock burst at site were investigated through the field investigation of site rock burst. Site sampling and the microscopic experimental were carried out in the area of rock burst. It was found that to a large extent, the macro mechanical behavior of phosphorite was in good agreement with micro-structure configuration and micro-mechanical behavior of mineral composition. The microscopic crack test demonstrated that the weak boundary of the phosphate rock grain boundary was the interface between dolomite and phosphate rock. The site-investigation found that rock burst occurred mostly in the area where the environment is dry after blasting and the dolomite content is high in rock strata. The criterion and the prevention strategies of rock-burst were finally proposed.
