The invention relates to a dredging method and a system for blocking a mine shaft, which can be widely applied to the treatment of an arch or blockage of materials in an underground mine, an underground mine, a mine and a surface storage ore bin. The system comprises a first tube (1), circular steel tube (2), third (3) pipe and valve (4); the first steel pipe (1) embedded in the chute reinforcement in concrete, and each first tube (1) connected with two circular steel tube (2), each two annular (pipe 2) between the upper and lower distance is 2 meters, the annular pipe (2) is welded on the 8 root of third steel pipe (3), third (3) in the circular steel tube (2) are uniformly arranged on the upper and lower two layers, third steel tubes (3) are in staggered arrangement, in the slide wall concrete pouring, to prevent 3 steel pipe is blocked; the first steel pipe (1) connected with the mine air supplying pipeline, and installation of the valve (4).

1.一种溜矿井堵塞的疏通方法,其特征在于所述方法包括如下步骤:1.1对溜井实施混凝土加固时,在混凝土中埋入第一钢管(1)、环形钢管(2),每根第一钢管(1)上连接两根环形钢管(2),每两根环形钢管(2)上下之间的距离为2米,环形钢管(2)上焊接有8根第三钢管(3),第三钢管(3)在环形钢管(2)上均匀布置,上下两层第三钢管(3)呈交错布置,在溜井壁混凝土浇筑时,要防止钢管3被堵塞;1.2溜井支护结束后,在矿井供风系统安装时,将位于溜井底部的第一钢管(1)与矿井供风管路连接,并安装阀门(4),并检查管路系统是否畅通;1.3溜井发生堵塞后,按照环形管(2)由低到高的顺序,依次开启第一钢管(1)上的阀门(4),将压缩空气通过第一钢管(1)、环形管(2)和第三钢管(3),将压缩空气送到溜井堵塞部位,利用压缩空气产生的动能对堵塞物料进行疏通;1.4当第一个阀门(4)开启后,若只听见压缩空气吹出的声音而无物料落下时,可关闭第一个阀门(4),开启第二个阀门(4),依次类推,直到有物料落下;1.5随着压缩空气的不断送出,溜井中堵塞、粘结成拱的物料不断被压缩空气吹落,特别是与溜井壁粘连且对“拱”基础遭到 ...
