(57) A blast modeling system may generate a site model based on blast input data. The blast input data may include blasthole data, bench information, and geology input data. The site model may comprise a plurality of distinct elements representing rock masses. Each element may have a geometric outline formed by connecting endpoints of one or more lines with arcs such that the endpoints of the one or more lines are indirectly coupled via the arcs. The blast modeling system may simulate a blast using the plurality of elements.

(57) As air inside a building (e.g., a data center or any building that generates heat) becomes heated, it rises and is received or captured by a heat containment and then expelled from the building. The hot air is not recycle, recirculated, or recooled. Hot air being expelled from the building creates a pressure differential in which the pressure at the hot side of the building (where the heat 10 containment is located) is lower than the cool side of the building. To this end, a chilling unit is installed at an opening of a building to supply cooled air at a constant rate. The chilling unit does not have an internal controller. Rather, an air conditioning (AC) unit of the building acts as an external controller. The AC unit is be set to maintain a target temperature and only runs when the temperature inside the building is above the target temperature. Fig. 11
