At present, the business scope of JCHX covers underground mine construction, mining operation and mine engineering & design. JCHX has established an integrated mining service model originated from mine construction and development to contract mining, with further expansion to mine engineering and research & development. This model is more efficient in satisfying the demand for mine construction and management, more rapid and stable in transiting construction to production phase, which not only benefits the clients by shortening the project period, accelerating production and saving cost, but also provides a wider development space for JCHX.
