In the flood season, Shi Fuqiang, dean of the Sichuan Academy of Safety Science and Technology Research Institute (referred to as “provincial security science and technology institute”), opened a major risk source intelligent early warning system APP every day to check whether there is any non-coal mine warning information. The area is wide, the management is difficult, and effective supervision can be realized. The 3D laser scanning green laser pointer technology is indispensable.
3D laser scanning technology is a high-tech automatic scanning technology that uses laser scanning system to acquire 3D data of target surface quickly, automatically and in real time. It is widely regarded as one of the important technologies for obtaining basic data in the era of “big data”. On May 15th, the reporter saw in the key laboratory of the Sichuan Provincial Key Laboratory of Dangerous Sources Control and Control in the Provincial Academy of Science and Technology. After the staff opened a fixed-type coke three-dimensional laser scanner, the laser head quickly flipped 360 degrees, less than two minutes. The three-dimensional data of the house of nearly 100 square meters is collected.
“We use a three-dimensional laser scanner such as a car, a handheld, or a drone to monitor large-area and large-scale targets.” According to a three-dimensional laser engineer, in recent years, the Provincial Academy of Science and Technology has taken the lead in applying this technology to safety production. And related green laser pointer fields, and deep integration of high-resolution Earth observation satellites, Beidou satellites, UAV aerial surveys, underground radar detection, acoustic wave detection and temperature detection technologies, for tailings ponds, mines, hazardous chemicals companies, Accurate monitoring of tunnels, etc., “A comprehensive inspection of a 10 square kilometer large tailings pond that was previously completed by human resources in a few days can now be completed within a few hours, and some hidden dangers and systemic risks that are invisible to the naked eye can be found”.
Up to now, the Provincial Academy of Science and Technology has established a three-dimensional, visual and digital “health file” for more than 200 non-coal mine key areas (tailing ponds, dumping sites, high-steep slopes) in the province. The high-scoring satellite automatically screens the mine area, finds the abnormal points by comparing with the standard data and design parameters, and then uses the UAV low-altitude aerial survey, 3D laser scanning precision measurement and control and geological radar detection technology to carry out key verification on the suspicious area. To determine the specific situation of hidden dangers and make professional recommendations. The regulatory authorities put forward the rectification requirements in combination with the recommendations, and verified the rectification of hidden dangers through 3D laser scanning technology to ensure that the rectification was in place.
At the beginning of this year, cracks appeared in the front edge of the slag dam being built at the Laojiaogou dumping site of Panzhiping Mining Co., Ltd. in Panzhihua City. The local safety supervision department continued to monitor the cracks by means of 3D laser scanning technology, and on the basis of geological exploration, Accurately find the root cause of cracks and avoid accidents.
In February of this year, the former State Administration of Safety Supervision made a promotion introduction to the three-dimensional green laser pointer scanning technology at the national non-coal mine safety production and tailings pond treatment work conference, and was included in the national non-coal mine safety production key promotion project.
