【摘要】 针对矸石和土壤填埋煤矿塌陷区的复垦方案,结合试验功能的需求,设计了一套测试矸石和土壤中的热量传递、水分迁移和气体流动的试验平台;该试验平台包括电加热模块、温度采集模块、湿度采集模块, CO2通气模块,CO2浓度采集模块。实现了矸石在土壤下长期堆积所发生化学反应对内部热量传递、水分迁移和气体流动的模拟;为以后分析矸石的填埋对土壤表层作物生长的影响提供可靠的数据结果。更多还原

【Abstract】 In allusion to reclamation project of gangue and soil landfill in coalmine subsidence areas, combined with the demand of test function, an experiment platform was designed to test heat transfer, moisture migration and gas flow which included electrical heating, temperature and moisture acquisition, the ventilation and concentration acquisition of CO2, realizing the simulation of chemical reaction generated by long-term accumulation of gangue in soil on internal heat transfer, moisture migration, gas flow, this could provide reliable data on analyzing the influence of gangue landfill on the growth of crop in surface soil.更多还原
