It agrees with calculations of the relation of microbic breath coefficient of the natural and broken soil is established the average and high negative level of influence of the mining industry activity on stability and intensity of processes of soil microbiological activity. Along with it is shown the increase by 2.5 times values of microbial breath coefficient in the turfy horizon of the primitive developed sandy soil at overgrowth of edatopes of a dump by grassy vegetation however by the decrease of substrate-induced breath level at the broken soil. According to quantitative structure of the celluloselytic microorganisms is established the reduction of their number by 1.8–2.1 times and is established activity on average for 20% in technogenic-broken soils. Analyzing dynamics of celluloselytic activity, it is established that the most vigorous cellulose-destroying activity microorganisms show in September-October when the percent of decomposition of fabric makes 25–38%. Confirmation of increase at autumn of celluloselytic activity of the soil is the increase almost twice in number of the cellulose-destroying microorganisms in comparison with the summer period.
