我国煤田自燃现象十分严重,致使煤资源遭受巨大损失。以宁夏贺兰山煤田为例,仅石炭井矿务局的大峰矿,每年就有100多万吨优质煤白白烧掉,损失人民币3000多万元。因此对煤田自燃进行调查,具有重要意义。多年来,煤炭部门对火区的调查和治理给予了高度重视,并使用了各种常规方法对煤田自燃状况进行调查。但由于矿区地质构造复杂.常规方法不能正常发挥作用,难以开展系统而全面的勘探工作,在精度上也难以满足需要。而利用热红外成像方法进行调查,则具有理想的效果,且不受地形因素的影响。在这次遥感调查中,使用了双水獭飞机、DS-1230定量双通道热红外扫描仪,DS-1830图像处理机及
Coal spontaneous combustion in China is very serious, resulting in enormous losses of coal resources. Taking the Helan Mountain coalfield in Ningxia as an example, only the Dafeng Mine of the Carboniferous Mine Bureau has more than 1 million tons of high-quality white coal burned annually, with a loss of more than 30 million yuan. Therefore, the investigation of coal spontaneous combustion is of great significance. Over the years, the coal sector has placed great emphasis on the investigation and management of fire areas and has used various conventional methods to investigate the status of coal spontaneous combustion. However, due to the complex geological structure of the mining area, conventional methods can not function properly and it is difficult to carry out systematic and comprehensive exploration work, which is also difficult to meet the needs in accuracy. The use of thermal infrared imaging method to investigate, it has the desired effect, and is not affected by the terrain. In this remote sensing survey, dual-otter aircraft, DS-1230 quantitative dual-channel thermal infrared scanner, DS-1830 image processor and
