Low rank coals such as brown coals are abundant but it is generally difficult to transport and store due to their high spontaneous combustibility. Therefore, it is necessary to develop upgrading processes of brown coals which will be utilized at the coal mines so that Japan can use such an abundant resource. In order to develop highly-efficient and environmentally-friendly processes, wehave to understand current situations of mining, pretreatment, and environmental measure at the coal mines. In this research, we visited several brown coal mines in Asia and performed a survey on mining method, pretreatment method, and environmental measure

褐煤等低阶煤储量丰富，但由于其高自燃性，一般难以运输和储存。因此，有必要开发褐煤的升级工艺，使其在煤矿中得到利用，以便日本能够利用如此丰富的资源。为了开发高效、环保的工艺，必须了解煤矿开采、预处理、环境治理的现状。在本研究中，我们访问了亚洲的几个褐煤矿山，并对采矿方法，预处理方法和环境措施进行了调查
