Water storage capacity has always been the core component of the underground water reservoir in open-pit coalmines. Taking the western underground water reservoir of Baorixile open-pit coalmine as the research background, boreholes in the waste dump overlying the underground water reservoir were designed and drilled, and the capacity characteristic...

... selection of the underground water reservoir in Baorixile open-pit coalmine is determined by the floor of No. 1 Coal Seam. According to the distribution of catchment areas, site selections of western and eastern underground water reservoirs of Baorixile open-pit coalmine are shown in Figure 1. Up to now, the construction of the western underground water reservoir has been successfully completed. ...

... 4 presents the calculation table of water storage capacity. Figure 10 shows the variation curve of layered water storage and cumulative water storage of underground water reservoir with the elevation. In this figure, Q L represents layered water storage; Q C represents cumulative water storage and h represents elevation of underground water reservoir. ...

In recent years, the slope of the bottom plate of the underground reservoir in the loose porous medium constructed in the middle and upper reaches of the river is relatively large, which makes the underground water surface incline to a certain slope as a whole, near-horizontal section will appear in front of the underground dam during continuous recharge. Given this situation, the definition and calculation of the characteristic index of the underground reservoir in line with the actual changes are carried out. The characteristic water level of the underground reservoir is defined based on the groundwater surface with a certain slope at the inclined level in the case of the lower dam (single dam) impoundment. The characteristic capacity is calculated through the water level at the typical section defined by the inclined surface. A new set of definition and calculation method based on the characteristic index of the underground reservoir with a dam on the inclined bottom plates is proposed and applied to the Rushan River underground reservoir, which more accurately reflects the water level change and the corresponding actual reservoir capacity during the operation of the underground reservoir.
Water supply system is an infrastructure for collection, storage, transmission, and distribution of water to homes, factories, irrigation of agricultural fields, etc. Water holds an important factor in growth of the city. Earlier, lakes and rivers are the major source of water supply to the cities and villages. The rivers followed their own path throughout the city and provided water to some specific areas. Due to this the new areas which were being developed would not have direct connection to the new areas, the people would have to look for other alternatives or use the water available from the underground water beds, by building wells. Water connection to different regions is setup in an organized manner. Even though everything is organized, but there are certain drawbacks such as improper detection in the leakage of pipe lines and failure in the proper use of technology to setup and organize. In this paper, an attempt has been made to rectify these problems by applying the concept of binary search tree. Also, we have discussed about how pipelines can be setup underground in a smooth manner and using IOT devices to detect leakages or breakages in the pipelines, so that the water is not wasted.
