Step 4) may further comprise the steps:
Step 41), in coal seam position data typing three-dimensional system of coordinates that all borings are disclosed and carry out smoothing processing, form and see seam accordingly;
Step 42), the coal seam positional information of every gang drill hole exposure is carried out match and draw position, actual coal seam and thickness;
Step 43), the framework real insight layer information of respectively holing again in three-dimensional geological model is described the spatial shape of coal bed, forms space, coal seam occurrence status.The spatial shape of coal bed comprises the shape of coal bed and the position in three-dimensional system of coordinate, and space, coal seam occurrence status comprises shape and the position of coal seam in three-dimensional system of coordinate.
The present invention is by making up four kinds of main boring stratigraphic models of underworkings construction, boring feature according to the down-hole construction, it is divided into the tunnel along layer boring, height is taken out tunnel boring, tunnel boring and the boring of stone door punching coal tunnel are taken out in the end, single hole and group hole are carried out the auxiliary design of three-dimensional, in conjunction with the disclosed geological information typing of drilling construction, coal petrography condition to borehole space form and control range thereof is carried out inverting and expression, under the man-machine interactively condition, exceptional conditions such as boring announcement regional tectonics are predicted, and export plane and the sectional drawing of all kinds of boring occurrence status, directly provide technical data for mine safety production.Above-described embodiment is applicable to the tunnel along layer boring, wherein the tunnel along layer boring for protected type intersect before inspecting hole, by designing a row or multi-row boring realization to regard to the detecting and controlling of square coal rock layer position, specifically referring to embodiment one.
Embodiment two
On the basis of embodiment one, as Fig. 5, shown in Figure 6, step 1) and step 2) between further comprising the steps of:
Step 11) is estimated 4 orientation, tunnel in coal geology model 1;
Step 12) is arranged in the construction tunnel 5 above or below working face of coal seam and is bored nest 6 positions;
Step 13) arranges height and takes out tunnel boring 7 or the end and take out 8 orientation of holing, tunnel;
Step 14) implements according to the preset bearing that height is taken out tunnel boring 7 or tunnel boring 8 is taken out at the end.
As the preferred embodiment of above-described embodiment, height is taken out lane boring or the end and is taken out in the width range that lane boring is distributed in about 15 meters of default heading both sides preferred 0-15 rice.Discharge by the gas of boring with this scope, can satisfy the safe construction in tunnel.
Height is taken out tunnel boring, is to bore nest in the construction tunnel to drill above working face of coal seam, and purpose is that the gas in the coal seam of underliing is carried out the extraction release of pressure; Tunnel boring is taken out at the end, is to drill in the construction tunnel below working face of coal seam, upwards wear a layer extraction coal seam gas pressure relief, and pump drainage is put base plate aquifer Zhong Shui.Step 11)-step 14) is applicable to that height is taken out tunnel boring and tunnel boring is taken out at the end.
The tunnel is drilled with along layer cloth and at first imports in the meter along layer tunnel, according to length and the width of threedimensional model results modification tunnel or coal seam piece; Increase according to actual needs again or reduce along layer boring.Can be single also can be many rounds, according to boring at drift section, help location parameter and design and construct, and high take out tunnel boring and the end take out tunnel boring before spudding in all need carry out the extraction release of pressure at the gas in the coal seam, by to coal seam and drift section Position Control, elder generation is the position, coal seam fixedly, design is spudded in and is bored the nest position again, by the design orientation layout of holing.
Each boring of typing actual coal rock layer geological information data that disclose in the process of drilling are revised design boring.At the design boring of four types of tunnels, carry out typing according to parameters such as the coal rock layer position data of the drilling track data that record in the on-the-spot drilling operation account, exposure, EXIT POINT position, water temperatures.Utilize the direct typing of form and file to import two kinds of forms, parameters such as the track that former design boring is disclosed, layer position are rationally revised, emphasis be indicate that boring discloses see the coal information point, control the physical location in coal seam.
Boring control area geological conditions inverting.Coal rock layer position data to typing is carried out preliminary treatment, and emphasis carries out smoothing processing to disclosing coal seam location point data, forms and sees seam accordingly.Disclose the coal seam positional information for many gang drills hole and simulate position, actual coal seam and thickness, each real insight layer information of holing of inverting reconstruct is expressed the spatial shape of coal bed in three-dimensional geological model, forms space, coal seam occurrence status.Set the discontinuous criterion in coal seam, and carry out man-machine interactively for the discontinuous breakpoint in coal seam occurring, disclose the control in coal seam according to a plurality of borings, emphasis is that the front geological conditions such as tomography that may exist in the coal seam are judged and prediction, for the safety in production of tunnel or work plane provides rational judgment technology parameter.
The boring design is exported with space expression and the plane of geology inversion result.According to boring design three-dimensional geological model result, coal seam, tunnel and bore position are accurately controlled, judge and adjust that the parameter that boring designs reaches technical requirement on design, can be directly to design result hole single hole or the plane of porous design, expression and the output of sectional drawing, by drilling construction unit is used.The tunnel is along the hole design plane output of many gang drills of layer boring, and boring row control both sides, tunnel, the place ahead respectively are 15m, and each row can design several borings as required, designs altogether usually about five borings.
After the down-hole site operation is finished in the boring design in the tunnel, form the reconstruction geological model of probing control area on geology inverting basis, comprise the information such as real trace, coal petrography of each boring, according to the coal rock layer feature of adjusting, directly export section as a result behind the results verification.The fault tectonic that prediction is existed is expressed simultaneously, for follow-up works such as tunnelling and working face extraction provide Technical Reference.Accompanying drawing 4 is the geological section after the geology inverting, the wherein position of fault that as seen dopes because the coal seam is discontinuous in the suitable layer boring of the heading control area.
It should be noted that at last: above each embodiment is not intended to limit only in order to technical scheme of the present invention to be described; Although the present invention has been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of various embodiments of the present invention technical scheme.
