North Shaanxi and Ningxia are extremely abundant in coal resources, with excellent geographical positions and transport facilities, suitable to build large size pithead power plants. This paper details the coal resources in North Shaanxi Province and Ningxia Autonomous Region, fuel coal and transportation conditions for building large size pithead power plants, and carries out the analyses of economic benefits and electricity prices of bidding for access to grid for the six recommended power plants. The analyses show that these power plants, after built up, will have strong competitive powers and make contributions for the sustainable development of power industry in North China and Shandong Province. 展开更多

In the course of pushing forward the overall growth capacities of the mining industry and getting adapted to the tense competition after China抯 entry into WTO, it is quite necessary to speed up the process of fostering large state-owned coal group enter-prises. This strategical proposal is made on the basis of a comprehensive analysis of the main problems challenges faced by the coal mining industry is made on. The main prob-lems with Chinese coal mining industries discussed include: over-competition with a low convergence, severe waste and loss of mine resources with poor exploitation techniques, disordered operation with few industrial entry barriers, heavy welfare burdens from low socialization. The accession of WTO provide Chinese coal mining industry with chances to push forward the reforms and structural shift in the enterprises, expedite the estab-lishment and perfect of coal mining market mechanism, expand their international market share as well as introduce foreign investment, and with challenges from high technology, knowledge economy, and information revolution. The solutions to the foster of large-scale coal mining group enterprises, as well as the possible points to note and the policy pro-posal are advanced. 展开更多
