煤层底板突水是受到多种因素影响的复杂现象,分析突水影响因素是突水机理研究组成部分,也是建立合理突水预测模型的前提。阐述影响赵家寨煤矿二1煤层底板突水因素,为该矿承压水害的预测预报和防治提供一定理论参考和依据。对于该矿区,查明摸清地质构造特别是断层产状尤为重要。最后针对突水影响因素给出水害防治措施建议。
Water inrush from seam floor is a complex phenomenon influenced by many factors. Analyzing the factors affecting water inrush is an integral part of water inrush mechanism and also a prerequisite for establishing a reasonable water inrush prediction model. The factors affecting the water inrush of 21 coal seam floor in Zhaojiazhai coal mine are expounded to provide some theoretical reference and basis for the prediction and control of the pressure water damage in this mine. For the mining area, it is particularly important to find out the geological structure, especially the fault shape. Finally, according to the influence factors of water inrush, suggestions of water damage prevention and control are given.
