浅井采用火砖砌炉子通风,每个火炉要300多块砖,价值十多元,工程结束后,又要工人拆移,既浪费劳动力也很不方便。现我们都利用爆出的石块代替火砖,在浮土掘井时,在井边挖小洞,利用土层做炉壁,靠井这边用石块和黄泥浆封住。风筒安装在井口下部6-7公寸处。采用这种就地取材的方法,既能及时解决通风问题,通风效率亦不受影响,并且经济实惠。
Shallow wells using fire brick ventilation stove, each stove to more than 300 bricks, the value of ten yuan, after the end of the project, but also demolition workers, both waste labor is also very inconvenient. Now we all use the exploding stones instead of fire bricks. When floating earth digs, we dig small holes on the side of the well, use the soil to make the wall of the furnace, and close the well with stones and yellow mud. Duct installed in the lower part of the well head 6-7 inches Department. This method of using local materials can not only solve the ventilation problem in time, but also the ventilation efficiency is not affected, and the economic benefits are obtained.
