In order to solve the problem that the influence of light intensity on solar cells is easily affected by the complexity of photovoltaic cell parameters in the past, it is proposed based on the influence of light intensity on the power generation performance of solar cells. By analyzing the electrical performance parameters of photovoltaic cell trough solar energy and determining the influencing factors, discarding other weakly related parameters, and designing targeted research programs, according to the study of the impact of light intensity and temperature on the battery temperature changes, the performance of photovoltaic power generation was understood. The output voltage and current of the maximum power point were obtained. By analyzing its relationship with influencing factors, the impact analysis on the power generation performance of photovoltaic cells was realized. The experimental results show that the open circuit voltage, short-circuit current, and maximum output power of solar cells increase with the increase of light intensity. Therefore, it can be known that the greater the light intensity, the better the power generation performance of the solar cell.

The traditional research method of fault diagnosis mechanism has poor stability, which leads to the difference of fault diagnosis and location results. Therefore, under the complex geological environment, a new research method of fault diagnosis mechanism of gear and bearing for coal mining equipment is proposed. This method calculates gears and bearings’ yield strength by analyzing coal mining equipment’s bearing capacity elasticity. According to the fitting degree, the equipment sample’s projection space is confirmed, the fault features of gear and bearing are extracted by segmentation algorithm, the optimal fitness is set by positioning algorithm, the location of fault center is obtained, and the fault mechanism diagnosis is studied. Experimental results show that compared with the traditional method, the proposed method is more stable, and the difference in fault diagnosis results is minimal. It can be seen that this method is more suitable for fault diagnosis of coal mining equipment.

“…Most of them only care about development, regardless of the carrying capacity of the ecological environment, only the current development, but not sustainable development and they have the idea of development first, then governance. The scientific development concept must be used to coordinate energy development and ecological protection (Gao et al, 2019).…”

Aiming at the destruction of the ecological environment of the comprehensive geological structure, the traditional restoration countermeasures have the problems of high input cost and low economic benefits. For this reason, the ecological environment destruction process and restoration countermeasures of the comprehensive geological structure were proposed. The common geological structure characteristics and the impact of activities on the ecological environment in the mining area were analyzed. Based on the analysis results, an evaluation system for the degree of damage to the ecological environment by mining activities was constructed. According to the expert scoring method, a rating standard was developed to measure the degree of damage to the ecological environment. Depending on the degree of damage, appropriate recovery measures were formulated. The experimental results show that compared with the traditional restoration countermeasures, considering the destruction of the ecological environment during the mining process of comprehensive geological structures, the proposed restoration countermeasures have the advantages of low cost and high economic benefits.
