Drawings
FIG. 1 is a schematic view of the operation of blasting the well plugging ballast;
labeled as: the device comprises a mine 1, a drilling machine operating platform 2, a casing 3, well plugging ballast 4, a supporting plate 5, a rope 6 and a blasting cartridge 7.
Detailed Description
The invention will be further described with reference to the accompanying drawings.
The construction method for quickly dredging the blocked mine comprises the following steps:
firstly, erecting a drilling machine operation platform 2 at a well plugging position of a mine 1, clearing loose ballast stones in an erecting range before erecting, and leveling uneven positions in the erecting range by adopting concrete; the erected drilling machine operation platform 2 is required to be smooth and can bear vibration impact load in the drilling process so as to meet the requirement of safe operation;
after the rig operation platform 2 is erected, hoisting the rig to the rig operation platform 2 and installing the rig in place; the drilling machine can be various, and is preferably a geological coring drilling machine; the drilling machine can be hoisted by a winch which is arranged on a construction site and is more than 3T;
step three, a drilling tool is installed on the drilling machine which is installed in place; drilling tools typically include drill rods and the like; when the drilling tool is installed, the drilling machine, the drilling tool and the casing 3 need to be checked repeatedly, and the drill rod and the casing with cracks and thread sliding can not be used uniformly;
step four, starting the drilling machine to drill holes and core, drilling holes along with the casing pipe in a mode that the casing pipe 3 follows the protective wall, and damaging the stress structure of the well plugging slag stones 4 in the shaft; if the hole forming of the follow pipe penetrates the well plugging slag stones 4, but the well plugging slag stones 4 are not broken, performing the operation of the fifth step;
and fifthly, removing the drilling tool and the drilling machine, not removing the casing 3, and then blasting the penetrated well plugging ballast 4.
The construction method is simple and easy to implement, the construction process is safe and reliable, the requirements on the construction technical level and the technical difficulty are not high, the construction method is easy to master, and the dredging of the blocked mine can be safely and efficiently completed.
Preferably, in the fourth step, when drilling the casing, the casing shoe connected to the casing 3 is hammered by a down-the-hole hammer, so that the casing 3 is synchronously followed; the sleeve 3 is a shaped product and can be repeatedly used for many times; the casing 3 can play a role of wall protection to prevent the rock mass from being disturbed and falling during the hole forming process; in addition, the inner diameter of the sleeve 3 is larger than the outer diameter of the drill rod, and the rigidity of the sleeve 3 is better, so that the drill rod can be prevented from bending, and the pore-forming quality is improved.
Referring to fig. 1, in step five, the blasting process is as follows:
A. selecting a plate with the width smaller than the diameter of the sleeve and the length larger than the diameter of the sleeve as a support plate 5, facilitating the connection of a rope 6 with the support plate 5, lowering the support plate 5 along the pipe wall of the sleeve 3 until the support plate 5 penetrates out of the bottom end of the sleeve 3, then pulling the rope 6 upwards to enable the two ends of the support plate 5 to be tightly attached to the bottom end of the sleeve 3, and finally tying the rope 6 and enabling the rope 6 to be in a tensioned state to fix the support plate 5; the rope 6 is generally tied;
B. processing a blasting cartridge 7 on the drilling machine operation platform 2 and connecting the blasting cartridge with a detonating cord, then lowering the blasting cartridge 7 onto the supporting plate 5 and making warning, and blasting operation is carried out after safety is determined;
C. and if the plugging ballast 4 is not cracked by one explosion, repeating the steps A and B until the plugging ballast 4 is cracked. If the mine is blocked in multiple sections or the single section is blocked longer, the method can be adopted for charging and blasting in sections until no well ballast 4 blocks in the shaft.
According to the blasting treatment mode, the blasting explosive cartridge 7 is positioned near the bottom of the well plugging ballast stone 4, so that the stress structure of the well plugging ballast stone 4 in a shaft is favorably damaged, the well plugging ballast stone 4 is effectively collapsed, the well plugging ballast stone 4 is far away from the drilling machine operation platform 2, and the construction safety is high.
