Black/white aerial photographs with visible light （1:35000） are used as main information source to fulfil aerial remote sensing survey on scale of 1:50000 in our project. Distribution of burnt rock and ignition boundary of coal seams in Xin-ming district （covered an area of 1300 km2 in shen-fu coalfied） had been indentified （trapped）. Author of this paper given an introduction to the methodology and results of burnt coal area investigation by means of remote sensing. Target of the investigation is an extinct-burnt area. The first task of the study started with basic geological characteristics investigation is to divide macro-lithotype of burnt rocks

determine its forming epoch and make approach to the mechanism of its genesis. The second task of the study is to establish preliminary interpreting indices by means of studying image features of burnt rock and ignition boundary

which is carried out in a known area selected in the light of existed data. The third task of the study is to complete the remote sensing investigation for burnt coal boundary all over the district

to replenish

molify

and perfect the original interpreting indices. During the investigation

interpretation was combined with survey; remote sensing was combined with conventional methods. Finally

the ignition boundaries of coal seams are trapped

the accuracy requirements are fulfilled through borehole examination.
