Collaborative development of co-existed and associated minerals in the coal series
There are many types of minerals associated with coal series,with large quantity and wide distribution,and they overlap with coal seams.Collaborative development of coal series minerals is a major strategic demand of the country.The superposition of mining rock activity and fluid migration law are the core common scientific issues of coordinated mining of co-existed and associated minerals.The superposition of mining stress,rock deformation,fractures,and movement are key factors affecting the coordinated mining of co-existed and associated minerals in coal series.The stability of interlayer rock layers,the continuity of interlayer rock fractures,and the displacement of fractured steps in ore layers(bodies)are key indicators for evaluating whether coordinated mining can be attained.By utilizing coor-dinated mining techniques such as zoning and staggered mining methods,as well as pollutant source iso-lation,synergistic control can be achieved to coordinate the environmental impact of mining.Due to the differences in the occurrence locations and states of associated minerals in the coal series,the core indus-trial links involved in their collaborative development industry chain also vary.Considering the compati-bility of different mining processes and equipment,various collaborative development models have been formed accordingly.At present,there are preliminary models or scenarios for the comprehensive deve-lopment of coal aluminum iron gallium(Xingxian model),coordinated mining of coal uranium(Ili Ba-sin),and coordinated development of water coal gas(Ordos).Technologies for co-mining of uranium and oil and gas through underground drilling in coal mines have been proposed,achieving feasible col-laborative development technology,safety,and environmental protection.The development of overlap-ping mineral rights can easily lead to mutual influence,inability to mine normally,and increased safety risks and environmental impacts.The allocation of mining rights for associated minerals in the coal series is a core issue in industrial development,and there is a critical need for industrial policy support to pro-mote high-quality development of the industry.Policy suggestions have been proposed for mining rights reform,comprehensive exploration,and collaborative development.Collaborative development enterprises of coal series co associated minerals can have three enterprise models:non-impact agreements signed by various mining enterprises,joint development of related mining enterprises with the main ore body as the main body,and the establishment of joint corporations for integrated development of over-lapping resources for collaborative development.
