Method of mapping and control of surfaces of tunnels in projective development w here it can be realized with the help of a computer. The method is characterized by the reception of the primary surveys by the total stations at the duration of constructional phases of a tunnel. It contributes to the forecasting of future excavations based according to the existing surface of excavations that were realized in the past. The current technical monitoring of tunnels under construction is not allowed (beyond the classical cross sections), a detailed and comprehensive monitoring of the project. As a result this contributes to the loss making of the project's quality, as well as to the to the bad cost estimation for a constructional company. The method of mapping and control of surfaces of tunnels in projective development, calculates cylindrically the points of the primary surveys with geometric adaptation of the proportional radius of each theoretical cross-section that is wished to be compared with the existing surface of a tunnel. The development of each arc of different radius with geometric passages of the proportional space where each point belongs, contributes in complete and precise development in the all length of arcs of radius until each point of measurement. As result of the transformation, it will be the completed information in the all length and width of a tunnel. The calculation of the algorithm of method is carried out with the aim to appear cylindrically but also absolutely at any point of the tunnel, information with regard to the future behavior of explosions. The future behavior of explosions examines the regions of explosions that were realized in the past. It presents how it could be a next explosion according to the geological criteria.
