Recently，Good news from the State Intellectual Property Office，The "A Machine Learning-Based Ground Fissure Identification and Extraction Method from UAV Images" completed by Hanjiawan Coal Company and China University of Mining and Technology obtained the national invention patent certificate，Scientific and technological innovation work adds another important achievement。
As understood，National invention patent is different from national utility model patent，Its creative review standards are higher，Need to have “outstanding substantive features and significant progress”，m88 casino reviewMore emphasis on breakthroughs、Originality、Novelty。At the same time，Except for preliminary review，Substantial review still required，Longer review period，The protection period is 20 years。
Land cracks are one of the geological and environmental problems caused by coal mining，May cause deformation of the building、Underground pipeline damage、Damaged farmland、Accelerated soil water evaporation、Vegetation damage、Problems such as water and soil erosion。Currently，The crack identification and extraction process mainly uses machine learning methods，But because the surface information of the mining area is too complex，There are many interference factors such as vegetation，Not only is it difficult to measure，At the same time, the accuracy cannot be guaranteed。
To solve the above problems，Hanjiawan Coal Company and China University of Mining and Technology cooperated to conduct research on "A Machine Learning-based Ground Fissure Identification and Extraction Method from UAV Images"。Applying machine learning algorithms to the identification of land cracks in drone images of mining areas，Greatly improves the efficiency and accuracy of crack identification，Facilitates the actual land reclamation m88 casino reviewprocess in mining areas，Know the location of cracks in time for landfilling，It can also be used in scientific research work to study the development rules of surface crack images caused by mining，Provide effective technical support for ecological management of mining areas。
In recent years，Hanjiawan Coal Company always adheres to the drive of technological innovation，Follow the principle of “practical + cutting-edge”，Gather strength to carry out scientific research and innovation among all employees，Cultivation of the company’s core competitive advantages。As of now，The company has completed more than 1,000 innovative projects of various types，Obtained 96 national invention patents and utility model patents，Producing economic benefits of more than 80 million yuan，Promote high-quality development to take greater steps。(Zhou Zhufeng, Marshal Lu)
