Open-pit mine monitoring videos are often severely affected by image degradation, mainly due to the limitations on monitoring equipment performance imposed by explosion-proof requirements, the obstruction by large equipment and structures within the mining area, and inadequate lighting caused by nighttime operations. These factors collectively lead to noisy images, low resolution, and insufficient illumination, which affect the clarity and visibility of the images, thereby negatively impacting production scheduling and worker safety monitoring. To address this issue, this study introduced an efficient image restoration technique specifically tailored to the degradation problems unique to open-pit mine monitoring videos. A novel simulation of the degradation process in open-pit mine monitoring videos was developed, designed to replicate image degradation scenarios caused by low light and obstructions typical in the mining environment, including image quality improvements under low-light conditions and explosion-proof constraints. Based on this, a large-scale dataset was constructed, and a deep learning network named LEDNet was proposed. The network was specifically designed to jointly enhance the brightness and clarity of low-light images, taking into account the interaction between low-light enhancement and deblurring tasks. This innovative approach not only significantly improves the quality of open-pit mine monitoring images but also provides an effective means to enhance the performance of monitoring systems in harsh environments, which is of great significance for improving production efficiency and ensuring operational safety. Extensive experiments demonstrate that the method performs excellently in processing images in real open-pit mine monitoring videos, effectively enhancing image visibility and clarity. %K 露天矿监控， %K 图像恢复， %K 低照度增强， %K 去模糊， %K 安全生产
