Different drilling and blasting strategies to improve blasting efficiency have been evaluated. The results of each strategy were compared by means of visual site investigation after blasting and calculating the total cost Petron of the broken rock. Site investigation had shown that the third strategy had overcome the problem of unexploded ANFO. Unexploded ANFO was not seen after the blasting and also visual inspection showed significant decrease in the number of oversize boulders. Another proper approach to evaluate different strategies is a comparison of unit production costs. Since the Objective is to minimize the production cost of per ton rock, then the resulting cost of each strategy should be calculated. For that reason, the comparable costs were estimated. These are drilling cost, blasting cost and secondary breaking (hydraulic hammer)cost.

As the deep development of Economic Globalization and Regional EconomicIntegration, international industries transfer to developing countries as well as the east industries transfer to central and western regions continuously. The government implements the Central Rise Strategy speedily so as to propel the development process of industrialization, urbanization and agriculture modernization. It's the critical period to realize Central Plains Rising and well-off society in an all-round way in the next ten years. In total, there are more opportunities than challenges based on so many challenges and opportunities.

With the low urbanization in central regions, the more needs and requirements about housing, transportation and comprehensive infrastructure are directly effect the active demand for mining equipments during a long period. Besides, the development of urbanization would directly drive the industrialization process, in return the industrialization would promote the other industries' development. According to rapid economic development at present, the large investment to infrastructure must lead to the strong requirements for mining machinery during the urbanization and industrialization.

As a member of engineering machinery group, Henan Hongxing Mining Machinery Company continuously innovate and improve the equipment to fully respond the governments' policy and motivate the central regions economy's development, which make the grinding mills a good sales performance and consistent reputation across our country at the same time. It is, however, only a starting point. Any analysis of fairness with regard to whether a mining company is paying its fair share should include not only income taxes, mining taxes or royalties but should arguably also include all taxes and payments to government by a mining company. This Summary of income and mining taxes and mining royalties does not include property taxes, VAT and other taxes broadly applicable to all businesses. As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing station. We also supply individual jaw crusher and Raymond mill as well as spare parts of them.
