Bài viết trình bày một mô hình toán học dựa trên lập trình tuyến tính số nguyên hỗn hợp cùng với phương pháp giải hiệu quả để giải quyết vấn đề lập kế hoạch khai thác dài hạn cho các mỏ đá vôi xi măng. | 58 Journal of Mining and Earth Sciences Vol. 61 Issue 5 2020 58 - 70 Developing a mathematical model to optimize long - term quarrying planing for limestone quarries producing cement in Vietnam Bao Dinh Tran 1 Trong Dinh Vu 2 Viet Van Pham 1 Tuan Anh Nguyen 1 An Dinh Nguyen 1 Giang Huong Thi Le 3 1 Department of Surface Mining Mining Faculty Hanoi University of Mining and Geology Vietnam 2 TU Bergakademie Freiberg 09599 Freiberg Germany 3 Faculty of General Education Hanoi University of Mining and Geology Hanoi Vietnam ARTICLE INFO ABSTRACT Article history Mathematical model researches in optimizing long - term quarrying Received 08th Sept. 2020 planning for limestone quarries supplying to the cememt factories have Accepted 29th Sept. 2020 not been popular in Vietnam. The paper shows a mathematical model Available online 10th Oct. 2020 based on Mixed Integer Linear Programming as well as effective method Keywords to cope with long - term quarrying planning for the quarries. Techniques Limestone quarry grouping block cells into a mining room and decision variable elimination Long term planning techniques was employed to reduce the size of the problem. This enable to form an optimal method with proper time. The model and the algorithm Mathematical model are an effective tool to conduct a long - term planning for the quarries Raw material enabling to supply the quatity and quality enough of raw materials to the Vietnam. factory. The model was demonstrated and practically evaluated when being applied and compared with one of the popularly commercial sofwares in mine schedule GEOVIA Mines.
