Abstract Three-dimensional laser scanning technology as the rise of a new mapping technology is a mapping GPS industry following the technological revolution after another, called "real replication technology.", but the application is not very widespread, particularly subsidence areas are mining area. Land reclamation is a production and construction activities and land damaged by natural disasters and take remediation measures, to reach for the use of the state's activities. Such as the document scanning Liuqiao Anhui coal mine subsidence, since coal mining Liuqiao such land subsidence occurred around the mine area. Land around the mines could not be applied, since the coal mining Moreover, making the land salinization, reducing the local land utilization, so its land reclamation, will make around Liuqiao coal mine ecological environment improved significantly, increasing land benefits can also make use of land mines people get more financial resources. This article was adopted a large number of three-dimensional laser scanning scanning area point cloud data, three-dimensional laser scanner by Lecia cyclone dedicated software for point cloud data processing, analysis, and to mine subsidence area accurate, intuitive spatial land information, reflecting subsidence area topographic map of the topography of the surrounding area in order to design mining subsidence land reclamation program.
