Abstract
The invention discloses a method for exploiting a surface mine slope deformation area. The exploiting method comprises the following steps: firstly, establishing an earth surface and deep hole displacement monitoring network for an end slope deformation area so as to determine the slope displacement direction; and then exploiting in the direction opposite to a slope, and discharging soil and pressing feet in a soil discharged space formed by exploiting. The method for exploiting the surface mine slope deformation area is used for discharging the soil and pressing the feed immediately after the soil discharged space is formed by exploiting disclosed coal at the lower part of the deformation area so as to enhance the treatment effect on slope sliding and deformation, so that the recycling rate of mineral resources embedded due to landslide is increased.
Description
Technical field
The present invention relates to opencast mining field, particularly a kind of exploitation method of open mine side slope deformed area.
Background technology
Current domestic surface mine adopts the technical scheme of cutting slope presser feet (exploiting after first cutting slope presser feet) to exploit landslide and deformed region to the improvement of slope sliding, deformed region.
The limitation of the exploitation method of this landslide and deformed region is comparatively large, and production technique is not perfect, and press the mineral resource recovery rate of burying low because of landslide, loss of mineral resources is larger.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of exploitation method of open mine side slope deformed area of simple and reasonable steps, deformed region bottom has been disclosed coal extraction and to have formed behind casting space casting presser feet immediately by the exploitation method of this open mine side slope deformed area, strengthen the regulation effect to slope sliding, distortion, improve and pressed the mineral resource recovery utilization rate of burying because of landslide.
For achieving the above object, the invention provides the exploitation method of open mine side slope deformed area, comprise the following steps: first, first set up end wall deformed region earth's surface and deep hole displacement monitoring net, to determine displacement direction of side slope; Then, just to displacement direction of side slope exploitation, and casting presser feet is carried out in the casting space that extraction is formed.
Preferably, in technique scheme, advance with the face width of 40m when just displacement direction of side slope being exploited.
Preferably, in technique scheme, when just displacement direction of side slope being exploited, coal seam is divided into multiple step.
Preferably, in technique scheme, when just displacement direction of side slope being exploited, coal seam is divided into two or three steps.
Preferably, in technique scheme, after casting presser feet, as deformation tendency slows down, displacement monitoring speed diminish or stable after, adopts two excavator cooperatings carry out fast extraction, fast in arrange.
Compared with prior art, the present invention has following beneficial effect: deformed region bottom has been disclosed coal extraction and to have formed behind casting space casting presser feet immediately by the exploitation method of this open mine side slope deformed area, strengthen the regulation effect to slope sliding, distortion, improve and pressed the mineral resource recovery utilization rate of burying because of landslide.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole manual and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
Exploitation method according to the open mine side slope deformed area of the specific embodiment of the invention comprises the following steps:
As shown in Figure 1, first, first set up end wall deformed region earth's surface and deep hole displacement monitoring net, according to monitored data, draw end wall displacement vector figure, determine displacement direction of side slope.
Then, just to displacement direction of side slope exploitation, and casting presser feet is carried out in the casting space that extraction is formed.
As shown in Figures 2 to 5, concrete exploitation method is as follows:
(1) face width with 40m from east side advances southwards, and the displacement direction of side slope that direction of propulsion and slope displacement monitoring obtain is contrary.During exploitation, coal seam is divided into n step (according to Coal Seam Thickness Change, n gets 2,3), when exploiting the first width, topmost step width is 40+ (n-1) × 30m, in east side, n=2, with WK10 excavator adopt dress, Automobile Transportation carries out back production, shoulder height 12m.
(2) after deformed region bottom having been disclosed coal extraction formation casting space, casting presser feet immediately; If deformation tendency slows down, displacement monitoring speed diminish or stable after, 2 excavator cooperatings can be adopted to carry out fast extraction, fast interior row, reduce the distortion of southeast side side slope, ensure the safety of ground installation (building, transmission line of electricity etc.) and underground installation (drainage pipe etc.); If stability of slope is in bad order in above-mentioned recovery process, a small amount of coal of foot step can be cast out and do not adopt, stay and do end side presser feet, to ensure the stability of end wall.
To sum up, deformed region bottom has been disclosed coal extraction and to have formed behind casting space casting presser feet immediately by the exploitation method of this open mine side slope deformed area, strengthen the regulation effect to slope sliding, distortion, improve and pressed the mineral resource recovery utilization rate of burying because of landslide.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
