The influence of the humanitarian component (sacred, religious, social factors) on the origin and initial development of mining activity, metallurgy origin, the first natural and technical knowledge accumulation and application forms are considered. The hypothesis of the metallurgy occurrence in the stable communities of primitive miners is considered. The ideology component of important technological inventions, created in an environment where both these phenomena were extremely close, is shown. The organizational forms of mining activity in which sacred factors played an extremely important role from archaic mining communities to medieval religious orders (in particular, Cistercians) were analyzed. The role of traditions, beliefs and professional knowledge in the formation of the special mining communities' nature from ancient time to the Middle Ages, their heritable resistance and isolation have been revealed. The possible ways of future mining progress are described, for which the scientists' and entrepreneurs' substandard ideas and predictions are used.

The construction of morphological model is considered for undesirable events regarding urban objects, as well as the consequences of such events, including interruption of operation, feasibility and time of restoration, material damage and casualties, ecological risks. Using this model, two-stage modified morphological analysis was conducted for two types of objects: pipe and tunnel depressed sewers. The results of comparison for depressed sewer crossings using the developed model are demonstrated both for the whole multitude of potential undesirable events and for the specific scenarios of sabotage, landslide, operational damage. The advantage of a tunneled depressed sewer over a pipe one is justified from the standpoint of minimization of technogenic and ecological risks of sewage draining.
