Coal industry is a capital intensive industry, which needs a lot of capital. From the development of mineral resources, the introduction of equipment, the expansion of scale to the final sales, this is inseparable from a strong capital injection. If the fund is interrupted in a certain link, the enterprise will face different degrees of difficulties. Coal supply chain financing can greatly alleviate the capital shortage of small and medium-sized enterprises in the chain, and meet the financing needs of different enterprises in the chain, so this business is very popular in most small and medium-sized coal enterprises.
