During the grout injection process, a large amount of slurry bled water will enter the underlying rock strata below the grouting layer. Under certain conditions, the slurry bled water may seep along the overlying rock layer into the water-conducting fractured zone (WCFZ), resulting in the increase of water inrush in the working face, which affects the production safety and the grouting effectiveness. Therefore, it is urgent to establish the prediction model of working face water inrush and establish a safe grouting layer selection method to prevent the grouting water from entering the working face in the process of grouting filling. In this article, a new identification and prediction method of working face water inrush of IOGI were proposed. According to the characteristics of seepage boundary, a “semi-ellipsoid” theoretical model of seepage boundary of slurry bled water was established, and a dimensionless Formula of the model parameters was constructed. The dimensionless Formula was solved based on the experimental results of influencing factors of seepage boundary. Based on the distribution characteristics of free water in grouting filling, the identification and prediction method of working face water inrush of IOGI were established. The prediction method was analyzed to the actual mine, and the correctness of the prediction method was verified.

Using the proposed current control technique, the method ensures precise power injection and synchronisation with the grid voltage.

An optimal wind turbine configuration has been identified by using dual rotor wind turbine (DRWT) technology with a novel blade design known as the humpback blade, which is inspired by the fins of humpback whales. This design features tubercles and ridges along the leading edge that extend over the last third of the blade's length. The innovative humpback blade design lowered the nominal angle of attack in comparison to conventional blades, which led to a significant boost in lift and a notable reduction in drag forces. This enhancement in the lift-to-drag ratio enabled more efficient rotation at lower wind speeds. Furthermore, single rotor turbines fitted with these blades showed improved energy extraction and decreased turbulence intensity behind the rotor, making them especially effective in DRWT setups. The results validated the benefits of the humpback blade design in dual rotor systems, where the new design enhanced the lift-to-drag ratio in both upwind and downwind positions, resulting in higher overall energy output than turbines with standard blades. As a result, different configurations of the DRWT have been tested and examined.
