Advanced drainage of the sides of a coal mine by horizontal wells with a camouflage cavity

Abstract

The article presents the results of experiments on models made of equivalent materials of the operability of wells with a camouflage cavity and comparison with the output of groundwater by a natural aquifer. In the experiment, the geometric, physical similarity of materials in the nature of the model was observed. The results obtained showed that when using wells with a camouflage cavity, not only increases the inflow of groundwater, but also decreases the peak loads of depression stresses on the array, as well as the moistening of rocks around the aquifer, in addition, a graph is shown of the rate of water outflow in time on which with the distribution of water inflow without peaks at the time of the formation of washouts. The conducted experiments have shown good performance of wells with camouflage cavities providing effective drainage of the instrument array.
