Abstract To ensure that water resources are not damaged during coal mining, the height of the water conducted zone in coal mining is explored in this study. When mining coal mines, the height of the water conducted zone is complex and unstable when making predictions. Therefore, the Internet of things perception technology is applied to solve the problem of inaccurate data collection. Moreover, the multiple regression analytical method is introduced to obtain the prediction equation for the height of the water conducted zone. The research results show as follows: by using the Internet of things sensing technology, when collecting data, the redundant and error data can be excluded before the data fusion, which can improve the validity of the data. The multiple regression analysis methods are used to summarize and conclude the data by using the linear regression method; therefore, the obtained prediction equation can accurately predict the height of the water conducted zone, which solves the problem caused by using traditional empirical equations in coal mining in the past that leads to a large error in the prediction height. By using the Internet of things perception technology to predict the height of the water conducted zone in coal mining, the collected data are more accurate and the prediction results are more effective. Therefore, this method can effectively protect water resources during coal mining. Keywords Water conducted zone . Perception technology . Multiple regression method . Linear regression
Introduction During coal mining, the overlying strata on the coal seam will also be affected, and the phenomenon of movement and damage will occur, resulting in deformation. The degree of these damages can be divided into fall zones, fissure zones, and curved sinking zones, in which the falling and fissure zones are called water conducted zones. Because the water conducted zone is at the lowest level, the development of the water conducted zone and the prediction of its height can be used to predict the amount of water in the mine and the retention plan of the safety coal pillars. In addition, it can also predict the safety of mining work under high water content coal seams.

Research on the development law and height of the water conducted zone is a prerequisite to ensure the safety of coal mining operations (Liu et al. 2017a). Scholars worldwide have studied the development law and height of the water conducted zone; in the meantime, studies in this area started earlier in foreign countries of China. Globally, scholars have put fo
