Research On Material Inventory Optimization Of A Coal Mine Enterprises

In recent years,the state has implemented supply-side reform and green mine construction in the energy industry.Coal mining companies are facing the dual pressures of development and environmental protection.Coal mining enterprises must not only ensure safe production and contribute to the country's economic growth,but also achieve green development while safeguarding the environment.However,due to the lack of optimism about the economic development at home and abroad in the past two years,many coal mining enterprises have been operating at a loss.Of course,this is inseparable from the extensive operation and management model of coal mining enterprises.Under the management of the company,material inventory often appears inconsistent with the actual accounts.At the same time,due to extensive management,a large number of sluggish materials appear,which not only increases the work intensity of the material management personnel,but also brings great difficulties to the material management work.The optimization of inventory in production not only refers to the optimization of inventory quantity,but also refers to the optimization of material classification.Due to the complex operating environment of coal mining enterprises and the various types of materials involved in coal production,problems such as high material inventory costs and difficult management have arisen.Therefore,in order to achieve more efficient inventory management and lower cost of materials stored in warehouse,the coal mine enterprises must improve the material inventory management methods and the material classification methods,and choose different inventory management strategies based on the classification results.At the beginning of this article,the current situation of material management stored in warehouses A coal mine enterprises is analyzed.Through the introduction of the current situation of materials in several warehouses,it leads to the current problems of coal mine enterprises A's material management,that is,the high storage cost of materials,the long material turnover time,the low turnover efficiency,the unfounded material classification,and chaotic material management.Then through a thorough analysis of the causes of the existing problems,and put forward to the inventory optimization strategy of first classifying the materials,then constructing the inventory management improvement method.According to the improvement idea,first analyze depth the factors affecting the coal mine material classification such as the importance of the material,the material consumption speed and other influencing factors,and use the ABC classification method to classify the influencing factors in two dimensions.Reasonable material classification can well promote the management of materials.After classifying materials into different categories,different ordering models should be selected according to different material categories based on Economic Order Quantity model(EOQ),and the appearance of sluggish materials should be paid attention to at all times.Then,the paper puts forward corresponding auxiliary measures for the material management and further optimization of A coal mine enterprises,such as process management,sluggish treatment,material procurement plan,etc.The proposal of these measures can better promote the management and optimization of material inventory,and realize the improvement of economic benefits of coal mine enterprises.At the end of the paper,the main use of A coal mine enterprises after the inventory optimization strategy to evaluate effect of material management,got A coal mine enterprises material procurement cost,dull cost,inventory cost is declining as A result,not only released liquidity,improve the economic benefits of the enterprise,for the enterprise in the same industry competition has played a huge promotion effect,More to the development of coal industry has an important supplement and reference significance.Although this article studies the optimization of the material inventory of A coal mine enterprises,through the analysis of the need for the main work of summary,it is found that there are still insufficient place in this article,The optimization theory of coal mine materials still need to be improved,and related management methods are available while economic development at the same time is still need to constantly improve and upgrade.I hope that there will be opportunities to further enrich and improve this research in the future.
