This paper deals with the carbophos nanomedium, occupying the boundary region, but at the same time possessing its own features. Of particular importance is the rupture of atomic-molecular space with chemical processes and micro- and macro-space with mechanical processes. Metastability of the state of the open coal-gas system, detachment of nanocomponents, nanostructure and fractal properties are manifested at bifurcations in the linear-asymptotic type of development. In coherent processes it is manifested in gas dynamic phenomena of bursts, in stable processes - in stable gas evolution during coal metamorphism and metageneration. Prediction horizons, uncertainty of conceptual interpretations, entropic character of coal formation-metageneration processes are different aspects of coal nanospace as a real-defined and spatial-temporal category.
