Abstract：In view of the problem of land expropriation, it is very important for seeking for the steep slope method technically and economically. This article presents the scheme of "one blasting for two mining width over benches", which improves the efficiency of equipment and makes the angle of working benches steep and provides a new way for relieving the pressure of land expropriation. In addition, the stability of the working slope in the open-pit coal mine is evaluated during the implementation of "one blasting for two mining width over benches " scheme.
