GAS IGNITION BY CW LASER IN MINE SHAFT
矿井下连续波激光点燃瓦斯的研究

The gas ignition temperature bears a relation to laser power and gas concentration in shaft, the expression is deduced by basing temperature distribution from rock breaking by laser. and by using the classical theory of thermal exlosion. The numerical calcutions are done for several rock and different gas concentrations,it is given the power thresholds to apply CW laser in mine shaft.
