Description
Technical field
The present invention relates to a kind of detection method of up exploitation Overburden Failure Law, be applicable to the down-hole and survey the up exploitation coal seam Overburden deformation and failure feature that underlies.
Background technology
In the coal seam group mining process, the mining sequence in each coal seam generally all adopts working from top down.But under some geology and production technique condition, according to the practical development needs of mine, at first many mines exploit underlying seam in the coal seam group mining process, thereby have formed the mining sequence of up exploitation.In up recovery process, if upper working face of coal seam is positioned at fissure zone or bending subsidence band scope that lower Seam Mining causes, upper volt stability of surrounding rocks of laneway in coal seam is poor, simultaneously, stay the coal column of establishing also to form the area of stress concentration of certain limit after adopt in lower coal seam in overlying rock, also can bring adverse effect to upper seam mining.For judging that lower seam mining is on the impact of up work plane position and the control of stope drift active workings stability, analyze the feasibility of up exploitation, the failure law that needs its overlying strata after under research, adopt in the coal seam, at present, domestic research method for the migration of the overlying strata under mining influence destructive characteristics, rule mainly contains two classes: a class is field measurement, and an other class is namely analog study.wherein the field measurement method has electrical method of network concurrency, the drilling fluid method, the borehole television method, ultrasonic wave through transmission technique etc., but ultrasonic wave, geological radar, the geophysical prospecting method technical requirementss such as the signal of telecommunication are high, on-the-spot disturbing factor is many and financial cost is higher, the present invention the down-hole by up exploitation on the volt heading base plate long distance measurement of construction hole in underlie coal seam or the coal column, utilize the up exploitation of the bore detecting instrument research Overburden Rock Failure feature after seam mining that underlies, the leak-off velocity of observation drilling fluid, return water color etc., and disclose near the lithology of rock stratum exploration hole in conjunction with the result that survey meter observation station obtains, the water guide slit band, caving zone height and bedding, the joint, structural plane development condition and the present positions such as crack, and disclose the underlie temporal and spatial evolution of coal seam Overburden Rock Failure of up recovery process according to the observed result of the coal seam goaf top of underliing of adopting rear different time, working face of coal seam position and roadway position in the up exploitation in colliery determined to have great importance.Simultaneously, for the up exploitation work plane safe working under the similar engineering technical condition provides Technical Reference, method is simple and convenient, directly perceived, accuracy is high.
Summary of the invention
The invention provides a kind of detection method of up exploitation Overburden Failure Law, to have disclosed the temporal and spatial evolution of Overburden Rock Failure in up recovery process, up exploitation work plane position and the reasonable problem of determining of roadway position under certain engineering condition have been solved.
The technology of the present invention thes contents are as follows:
A. by in the underground construction long drilled holes, this boring is positioned at heading in up exploitation, in order to observe diverse location and to adopt the rear different time coal seam goaf overlying strata strata structure variation characteristic that underlies.
B. in the drilling construction process, adopt the drilling fluid method to measure the Overburden Rock Failure height, record the consumption, drilling water level, rate of penetration etc. of drilling fluid in drilling process to measure height of water flowing fractured zone, according to creeping into middle bit freezing, fall the anomaly mensuration caving zone height such as brill, by returning water color judgement lithology.
C. drilling construction complete after, adopt the bore detecting instrument to extend in described exploration hole the structural plane development condition such as underlie coal seam goaf overlying strata bedding, joint, crack and destructive characteristics thereof observed, recorded and analyze.Draw the temporal and spatial evolution of overlying strata according to the result of detection comparative analysis of each boring.
Beneficial effect of the present invention: the present invention can overcome the shortcoming of other field measurement methods, the down-hole by up exploitation on the volt heading base plate long distance measurement of construction hole in underlie coal seam or the coal column, utilize the up exploitation of the bore detecting instrument research Overburden Rock Failure feature after seam mining that underlies, and disclose the underlie temporal and spatial evolution of coal seam Overburden Rock Failure of up recovery process according to the observed result of the coal seam goaf top of underliing of adopting rear different time, working face of coal seam position and roadway position in the up exploitation in colliery determined to have great importance.Simultaneously, for the up exploitation work plane safe working under the similar engineering technical condition provides Technical Reference, method is simple and convenient, directly perceived, accuracy is high.
