Research on the optimized allocation of sandstone mineral under the integration of Beijing, Tianjin and Hebei province:based on the third round of mineral resources planning

The issuance of the outline of the Beijing-Tianjin-Hebei collaborative development plan in April 2015 marks a crucial period for the coordinated development of Beijing-Tianjin-Hebei region to make major breakthroughs in its all-round promotion.In order to better support the coordinated development of infrastructure construction and ensure the basic raw material of sand and gravel minerals, the author studies the development strategy of gravel in Beijing-Tianjin-Hebei region and its surrounding areas.Based on the third round of mineral resources planning in Beijing, Tianjin, Hebei, Liaoning, Inner Mongolia, Shanxi, Henan and Shandong provinces, development orientation has four characteristics:the mining total reducts、the forbidden mining space expands、the open-pit mining methods are bound, prohibit (limit) part of the mining.From the perspectives of total amount, space and industry, the situation is analyzed:the gap of supply and demand is large, the constraints on environmental protection are tighter, the gravel industry ushers in the development of the great era, and finally the paper proposes five policy suggestions.
