冒顶给煤矿带来很大的危害,所以各国都致力于研究用各种仪器以便及时向人们发出预报,避免事故的发生。美国现已有几百家采矿公司应用了遥感技术。 什么是遥感技术呢? 遥感技术就是利用光学的、电子学的和电子光学的遥感仪器,从高空或远距离处接收被测物体反射或辐射的电磁波信息,加工处理成为能识别的图象或计算机用的记录磁带,以揭示大气的环境、陆地矿藏、海洋深度和其它物体的形状,种类,性质及其变化的一种测试技术。 煤矿所应用遥感技术首先是标明特定区域以及煤矿所在地,标出这些区域的经纬度和标志。由地球资源卫星从600英里左右 Fall to the top of the coal mine to bring great harm, so all countries are committed to using a variety of instruments to study in a timely manner to issue forecasts to prevent accidents. Hundreds of mining companies in the United States now use remote sensing technology. What is remote sensing technology? Remote sensing technology is the use of optical, electronic and electronic optics remote sensing instruments, from high altitude or long distance to receive measured objects reflected or radiated electromagnetic wave information, processed into a recognizable image or computer A recording tape used to uncover the atmospheric environment, terrestrial deposits, ocean depth and the shape, type, nature and variation of other objects as a test technique. The remote sensing technology used in coal mines first identifies the specific area and the location of the coal mine, with the latitude and longitude of these areas marked.
