Based on the function relation between the high temperature heat damage index and the influence factors, the linear model was used to describe the weight coefficient of each heat damage factor by using the synthesis correlation of multiple factors. The historical values of the influencing factors were used to make statistical calculation of the heat damage index model of crab culture in Hongze Lake Beach, which achieved good effects when applied in the meteorological operation of river crab culture.展开更多
平顶山矿区部分矿井开采深度已达千米,综采工作面高温高湿等热害问题日益严重。针对平煤股份十矿33010工作面埋深超千米、地温梯度大、温度高湿度大的客观地质条件,与格力电器公司进行合作研发局部制冷降温除湿系统,研制出满足矿井需求...平顶山矿区部分矿井开采深度已达千米,综采工作面高温高湿等热害问题日益严重。针对平煤股份十矿33010工作面埋深超千米、地温梯度大、温度高湿度大的客观地质条件,与格力电器公司进行合作研发局部制冷降温除湿系统,研制出满足矿井需求的多机头、大冷量、超高压比、高运行范围、低出水温度要求的采煤工作面局部制冷降温除湿设备。工程应用结果表明:格力电器公司3台制冷主机总制冷量达到2000 k W,采煤工作面温度最大降幅12℃,平均降低8.5℃;湿度最大降幅35%,平均降低25%,降温除湿效果明显,极大地改善了职工作业环境,有力促进了矿井生产效率的提升。展开更多
