纳沃伊矿冶公司穆龙陶露天矿位于乌兹别克斯坦的克齐尔-库姆沙漠,气候炎热。露天矿坑总容积约7亿m~3。不久的将来,该矿将转为深凹露天矿,目前已经出现的深凹露天开采的一些不良后果还将进一步恶化。现阶段由汽车运输所造成的露天矿内有害气体含量的增高就已迫使临时停止作业,以便把有害成分含量降低到许可限界,这就足以说明问题了。1990年,穆 Navoi Mining and Metallurgical Company Mu Longtao open-pit mine is located in the climate of Kozl-Qom Desert in Uzbekistan. Open pit total volume of about 700 million m ~ 3. In the near future, the mine will be converted to a deep-pit open-pit mine and some of the adverse consequences of the deep-pit open-pit mining that has emerged so far will be further aggravated. At this stage, the increase of the harmful gas content in open-pit mines caused by motor transport has forced the temporary stoppage of operations so as to reduce the content of harmful components to a limit, which is enough to explain the problem. In 1990, Mu
