Abstract

The invention discloses a kind of method of coal mine hard heading tunnelling footage, specifically is exactly the method for perforating blast firing of powder charge.The outstanding advantage of this method is that perforating is carried out synchronously with the dress hammer drill, makes full use of man-hour.To be section Lower Half eye determine each angle according to the degree of depth of the height of hammer drill and eye to specific practice.Computational methods are according to leg-of-mutton Pythagorean theorem.How much deciding of the dress method of roasting and boiling as two means of processing crude drugs and powder charge according to formation hardness.The mine that the present invention adapts to arbitrary formation hardness uses.

Description

The present invention relates to a kind of method of coal mine hard heading tunnelling footage, particularly the method for coal mine hard heading tunnelling footage perforating breeching medicine.
At present, Coal Production generally adopts the support comprehensive winning machine of import and the comprehensive mechanical of domestic production, accelerated coal mining speed, but hard heading tunnelling footage still uses traditional perforating blast firing of powder charge method, can not be supporting with comprehensive machine exploitation, and this traditional tunnelling footage method labour intensity is big, and safety factor is little.In real work, beat the waste that upper eye can not load the limit, dress can not perforating during waste, influence developing manufacturing schedule, the needs of adopting are combined in the incompatibility bank, have greatly influenced coal mining output.
The object of the present invention is to provide a kind of man-hour, safe and reliable that makes full use of, adapt to and combine the coal mine hard heading tunnelling footage method of adopting, to overcome above-mentioned the deficiencies in the prior art, by retrieval, this method is still unmanned to be used.
The object of the present invention is achieved like this: it comprises perforating, the powder charge step of tunnelling footage.Its special character is: in the drilling depth process, remove waste and perforating step and carry out simultaneously.The excavation method of beating of section Lower Half eye is: the number and the ordering of eye are set according to the degree of depth of formation hardness, eye, wherein the eyeground distance of first, second, third row's eye equates, its angle is according to the depth calculation of the height and the eye of waste, and calculating theorem is triangle Pythagorean theorem.The 4th row's eye is according to the hardness of rock and the degree of depth setting of eye.The loading method of the roasting and boiling as two means of processing crude drugs that matches with it is: head crash of thunder pipe and roasting and boiling as two means of processing crude drugs are loaded on the first row middle part eye, two crash of thunder pipes and roasting and boiling as two means of processing crude drugs are loaded on first row's second on the end limit and the second row middle part eye, three crashs of thunder are managed and roasting and boiling as two means of processing crude drugs is loaded on first first on row's end limit, second row holds second and the 3rd on the limit to arrange the 3rd on end limit, the 4th crash of thunder pipe and roasting and boiling as two means of processing crude drugs are loaded on second first on row's end limit and the 3rd row holds second on limit, in order to reach the explosion purpose, ring three eyes that maximum detonator of number and roasting and boiling as two means of processing crude drugs are loaded on the 3rd first on row's end limit and middle.
Purpose of the present invention can also reach by following measure, and the explosive payload of intraocular is directly proportional with formation hardness.Rock is hard more, and the dose in the eye is big more, so that developing smoothly.
Embodiment describes the present invention in detail below in conjunction with accompanying drawing
Accompanying drawing is the floor map of perforating powder charge of the present invention.
Main technical schemes of the present invention has 2 points: the one, and the direction of perforating and angle, the 2nd, the sequence of loading of charge explosion, on the developing section, the same prior art of other play, the technical scheme of perforating of the present invention is, on the play of section Lower Half eye, its concrete grammar is, be as the criterion with rock, the geological condition of opening the colliery, Luan, section Lower Half eye is designed to four rows, and first three arranges eye, equates with the distance between the eyeground between the eye mouth, to calculate the angle of each according to the degree of depth of the height of waste and perforating, specific embodiments of the invention such as following table:
The layout of the 4th row's eye will design according to the hardness of rock and the degree of depth of eye, if first three row's eye has been enough to can reach the exploitation purpose to the explosion of full stubble kiln well, that petty the 4th row's eye of just needn't making a call to, otherwise will arrange to arrange the 4th row's eye, the degree of depth of its mouth distance, eye and eyeground distance are with first three row.The order of breeching medicine is another technical scheme of the present invention, at first 5 eyes in centre (1) of first row's eye are adorned a crash of thunder pipe and a roasting and boiling as two means of processing crude drugs, the first row end limit second (2) and second row's middle part eye (3) are adorned two and are thundering and manage and roasting and boiling as two means of processing crude drugs, three crash of thunder pipes and roasting and boiling as two means of processing crude drugs are loaded on first row's end first on limit (4), second row's end second on limit (5), the 3rd row's end the 3rd on limit (6), the 4th crash of thunder pipe and roasting and boiling as two means of processing crude drugs are loaded on second row's end first on limit (7), the 3rd row's end second on limit (8), the 3rd row's end limit eye (9) and middle three eyes (10) will be adorned detonator and ring maximum detonator and the roasting and boiling as two means of processing crude drugs of number.
Come tunnelling footage with said method, during work, waste just need not be removed and can beat the eye of full stubble kiln, and after blowing out, blasting fume is got rid of the eye that just can at once make a call to second batch of kiln.Solved the contradiction of dress waste and perforating in the traditional method, the energy continuous operation, that is: the drilling depth forward of drilling and blasting, the back continuously adorns waste.
Compare traditional drilling depth method, outstanding advantage of the present invention is: make full use of man-hour, dress waste and perforating can be carried out simultaneously, operating efficiency improves 1.5 times, safety factor is big, because the layout of eye is decided angle according to the degree of depth of the hardness of rock and waste, it is safe and reliable to work together, can form a complete production network with comprehensive machine, output of coal improves greatly.
