摘要
针对露天开采行业高质量发展过程中,矿山粉尘带来的一系列生态环保问题日益凸显,采用无人机技术对露天矿山粉尘立体化分布状态进行量化描述。研究提出了基于无人机平台的露天矿山粉尘监测技术,并在安家岭露天煤矿成功应用,获取了采场粉尘浓度分布云图。监测结果表明:安家岭露天煤矿采场内冬季PM_(2.5)扩散主要由两部分组成:第一部分为标高1300~1325m空域的PM_(2.5),主要呈现垂直湍流扩散;第二部分为高于标高1325m空域的PM_(2.5),表现为高空水平输送扩散。采场上方空域中的局部逆温、等温现象是安家岭露天煤矿冬季PM_(2.5)积聚的主要原因。
Aiming at the increasingly prominent problems of ecological environmental protection brought by mine dust,a dust monitoring technology based on unmanned aerial vehicle platform is proposed,which is successfully applied in Anjialing Openpit Coal Mine,and the distribution cloud map of dust concentration in mine stope is obtained.The monitoring results show that the PM_(2.5) diffusion in Anjialing Open-pit Coal Mine in winter is mainly composed of two parts:the first part is PM_(2.5) within the elevation of 1300m to 1325m which mainly diffuses in vertical turbulent;the second part is PM_(2.5) in the airspace above the elevation of 1325m,which transmits and diffuses horizontally at high altitude.The local inversion and isothermal phenomena in the airspace above the stope are the main reasons for PM_(2.5) accumulation in winter in Anjialing Open-pit Coal Mine.
