随着煤矿采煤技术与速度的提高，煤矿区井下排水也随之增加，从而改变了水环境的天然状态，也改变了资源之间的自然环境转化关系，增加了河流水源和农田淋溶层的钠吸附比和残留Na2CO3的数值，使衣作物受到了损害，农田质量也受到了影响。这种污染现象已成为当今煤矿地区的主要公害之一． With the improvement of coal mining technology and speed, underground drainage in coal mines also increases, thus changing the natural state of water environment and changing the natural environment transformation relationship between resources, increasing the river water source and farmland leaching layer The sodium adsorption ratio and the residual value of Na2CO3, so that clothing crops have been damaged, farmland quality has also been affected. This pollution has become one of the major public hazards in today’s coal mines.
