Abstract
The invention belongs to an accumulated water control method, and particularly relates to a coal mine working surface goaf accumulated water control process, which solves the problems of unsafety of under-frame operation and great work intensity of workers in the goaf accumulated water discharge process using a pump discharging method. The coal mine working surface goaf accumulated water control process comprises the following concrete construction steps of: (1) digging a drainage ditch with the width of 0.5m and the depth of 0.4m which leads to a panel water sump; (2) carrying out drilling construction; and (3) discharging out accumulated water in a goaf through drill holes after the drilling is completed. The coal mine working surface goaf accumulated water control process has the beneficial effects that personnel do not need to enter a position under a support frame for operation; the personal safety of accumulated water discharging personnel is ensured; the workload can be properly reduced; and the labor and the materials are also saved.
Description
Technical field
The invention belongs to a kind of long-pending water tackling method, specifically a kind of coal mine working face goaf ponding is administered technique.
Background technology
At present, in fully-mechanized mining working exploitation process, the in the situation that of the water outlet of the Laoshan (force piece rear side), the general way discharge goaf ponding that adopts pump row, in order to discharge in ponding process, need the facility such as carrying water pump of people section chief's distance, the unsafe problem of operation under the large and frame of hand labor intensity.The present invention, for current this situation, need to take new improvement method to make personnel without entering support below operation, and ensure discharge ponding personnel's personal safety.
Summary of the invention
There is the unsafe problem of operation under the large and frame of hand labor intensity in order to solve pump row way discharge goaf ponding in the present invention, provides a kind of coal mine working face goaf ponding to administer technique.
A kind of coal mine working face goaf ponding is administered technique, and Specific construction step is as follows: 1) digging wide is 0.5 meter, is gutter to the panel sump of 0.4 meter deeply, treats that gutter digs, bed board on gutter.
2) carry out drilling construction; Before construction drill, dig gutter to the panel sump of wide 0.5* dark 0.4, when gutter digs, machine fortune team locking belt, treats that gutter digs, and on ditch bed board, prevent that coal slime from falling in ditch, can spud in, first by 10m orifice tube injection hole, install after high pressure valve by designing requirement construction drill.
3) after boring, the ponding in goaf is discharged by boring, and draining immediately after boring should be noted that 1, determines whether to install U-shaped elbow according to boring water yield in drainage procedure, 2, the inspection of toxic and harmful, emphasis is hydrogen sulfide gas.
At construction sequence second step, to construct altogether six and hole, in chamber, left side is apart from end 0.5m position, and construct respectively 1#, 2#, 3# boring, design hole depth and be respectively 35m, 32m, 30m; Chamber is just front apart from the construction of base plate 0.5m position 4#, 5#, 6# boring, hole depth difference: 35m, 32m, 30m.
compared with prior art, beneficial effect of the present invention is personnel without entering support below operation, has ensured discharge ponding personnel's personal safety, can suitably reduce workload, has saved again human and material resources.

Detailed description of the invention
a kind of coal mine working face goaf ponding is administered technique, and Specific construction step is as follows: 1) digging wide is 0.5 meter, is gutter to the panel sump of 0.4 meter deeply, treats that gutter digs, bed board on gutter;
2) carry out drilling construction; Before construction drill, dig gutter to the panel sump of wide 0.5* dark 0.4, when gutter digs, machine fortune team locking belt, treats that gutter digs, and on ditch bed board, prevent that coal slime from falling in ditch, can spud in, first by 10m orifice tube injection hole, install after high pressure valve by designing requirement construction drill;
3) after boring, the ponding in goaf is discharged by boring, and draining immediately after boring should be noted that 1, determines whether to install U-shaped elbow according to boring water yield in drainage procedure, 2, the inspection of toxic and harmful, emphasis is hydrogen sulfide gas.
As shown in Figure 1, at construction sequence second step, construct altogether six and hole, in chamber, left side is apart from end 0.5m position, and construct respectively 1#, 2#, 3# boring, design hole depth and be respectively 35m, 32m, 30m; Chamber is just front apart from the construction of base plate 0.5m position 4#, 5#, 6# boring, hole depth difference: 35m, 32m, 30m.
