The statuses of the stresses and strains and the varieties of the plastic area were simulated in the whole rock and coal pillars. The characters of stresses and deformation of the gob area of the coalmine were analyzed and evaluated after the site built in weathering. Moreover, the long-term stability of the gob area was predicted. As a result, the deformation of the gob area under the site is not been finished, and there is the danger that the gob site will collapsing as a whole; therefore, relative measures must be taken.展开更多

Since most of the power generation of the hydropower station is completed by operating the hydropower unit, if there is a problem or fault, the hydropower unit is easy to seriously affect the power generation of the hydropower station. Due to the long operation time of hydro generator, the fault is imminent. In order to minimize a series of losses caused by such faults, relevant technicians shall identify and clarify common faults, inspect and maintain these faults and problems, and effectively improve the safety and stability of hydraulic units.展开更多

In the report to the 19th CPC National Congress, it is clearly pointed out that rural revitalization is the main content of the development of The Times. It is necessary to innovate the rural collective property rights system, reasonably safeguard the vital interests of farmers, highlight the legitimate rights and interests of rural collective economic organizations, and realize the all-round development of rural collective economy. The capital assets and resources of rural collective economic organizations are based on the specific rural members. The comprehensive development of rural economy is the fundamental premise and important foundation of the new rural construction, and the farmers are on the road to getting rich and become the key point of development. The management and application of rural collective "three capital" is the fundamental problem of current concern to the farmers, and has played a positive role in stabilizing social development. Therefore, it is necessary to strengthen the management of "foreign investment" under rural revitalization and promote the all-round development of rural areas.展开更多

Due to the change of investment situation, the number of domestic chlor-alkali enterprises has increased, and the problems of global overcapacity and homogenization of products are frequent, which will intensify the competition in the caustic soda market and put the domestic chlor-alkali industry in an unprecedented competitive situation. Therefore, relevant personnel in the chlor-alkali industry must explore effective cost management and control methods to effectively address the challenge of cost-effectiveness and realize the further development of the chlor-alkali industry.展开更多

With the rapid development of social economy and the reduction of urban construction land, it is inevitable that there will be a large number of skyscrapers, and a large number of electronic equipment will be installed during the construction. Because of the intelligent characteristics of the comprehensive building, its utilization rate is much higher than that of the traditional building. Therefore, the construction of electrical engineering and land protection requirements are higher. In order to minimize safety risks and create a good living and working environment for users, construction techniques must be strictly controlled during electronic installation and related installations must be properly managed. In addition, there is a need to protect the earth and improve the electrical safety of electromechanical equipment in high-rise buildings.展开更多
