The invention discloses a method for identifying spam sources based on frequency and called distribution rules, including: setting the short message frequency threshold, that is, the maximum threshold of the number of short messages sent by the calling source within the set time granularity range, when the set When the number of short messages sent by the calling source within the time granularity exceeds the SMS frequency threshold, the short messages of the calling source will be monitored; set the called number dispersion rule, that is, monitor the calling source within the set time granularity Dispersion rules of called numbers for SMS sending. When the sending behavior of the calling source conforms to the called number dispersion rules within the set time granularity, the calling source is determined to be a spam source. The invention intercepts short messages according to the method of combining called rules and frequency of spam short messages, adopts calling source monitoring and adds calling sources conforming to called dispersion characteristics into blacklist.

The present invention relates to a method for ecological restoration of gullies and plateau slopes in the gully area of ​​the Loess Plateau in the east of Longdong. Combining with topographic maps, the slope landform, erosion degree, and groundwater distribution are analyzed to match the corresponding slope types and slopes. Types include: (1) large slopes with large area cut and fill areas; (2) large slopes that are developing and surrounding conditions do not allow large area cut and fill works; (3) large slopes with sliding Small-scale landslides with low risk of collapse, good overall stability, and areas where there is a risk of wedge-shaped sliding in landslides and unstable slopes; (4) small slopes with tension cracks at the rear edge of the slope; (5) not allowed (6) There are buildings and structures that need to be protected. On the basis of maximally protecting the original topography, landform and ecological base of the Loess Plateau, the present invention can realize point-to-point precise restoration for gully areas of the Longdong Loess Plateau with different topography and topography.

The invention provides a method for detecting a hidden water-conducting structure in the deep part of a working face, which belongs to the technical field of coal mine operation area detection, monitoring and control, and includes the following steps: 1) before the mining of the working face, adopt the underground transient electromagnetic detection method and / or microseismic Monitoring method, to find out the spatial distribution of low-resistance abnormal areas within the scope of mining influence; 2) Use the downhole drilling method and / or the ground horizontal branch hole drilling method for drilling verification; if water gushes out in the drilling, Then it is considered that there is a water-conducting structure in the low-resistance abnormal area; wherein, the borehole runs through the low-resistance abnormal area, and the distance between the borehole and the central axis of the low-resistance abnormal area is greater than the distance from the top of the low-resistance abnormal area It is equal to 30m. The invention also provides a treatment method for the hidden water-conducting structure in the deep part of the working face. The method for detecting and controlling the hidden water-conducting structure in the deep part of the working face provided by the invention has accurate drilling results.

The invention discloses a subsidence basin region division method and electronic equipment. The method includes: obtaining the excavation height, excavation width, and excavation depth, and monitoring the excavation length to obtain the current excavation length; according to the excavation The height, the excavation width, and the current excavation length determine a plurality of outer influence zone parameters for the outer influence zone outside the excavation space, a plurality of inner influence zone parameters for the inner influence zone inside the excavation space, and inner influence Multiple subsidence area parameters for subsidence basin regions within the region. The invention dynamically divides the subsidence area by parameters, facilitates the implementation of subsidence monitoring and precise management of the subsidence area, maximizes the self-repair property of the surface, reduces manual intervention, and realizes the self-balance of the surface ecosystem. At the same time, the calculation method is simple and practical, which can realize the regional division of subsidence basins under different mining conditions, and can be used for surface subsidence prediction, control, reclamation and ecological restoration management.

The invention discloses a deep-lying karst region water seal reinforced roadbed structure. The structure mainly comprises a roadbed (1), a cast-in-situ concrete slab (2), a bore hole (3), a slurry radiation area (4), a water flow (5), a pre-stress longitudinal beam (6), a cave (7), an independent base (8), a pre-stress crossbeam (9), a grouting pipe (12) and a slurry radiation hole (13). The water flow (5) and the cave (7) are isolated by the slurry radiation area (4) through a curtain grouting technology to prevent the growth of the cave; and the pre-stress longitudinal beam (6) and the pre-stress crossbeam (9) are used in the roadbed area above the cave (7) to support the pressure applied to the cast-in-situ concrete slab (2) by the roadbed (2), and the independent base (8) provides supporting force for the pre-stress beams. The structure can effectively processes large caves with the depths being greater than 10 m, effectively isolates the water flow, prevents the growth of the cave, has guaranteed stability, is simple to construct, is economic and reliable, and has wide application prospect.

The invention discloses a positional grouting reinforcement method for controlling groundwater seepage damage in foundation pit engineering. The method is divided into two different degrees: in the case of a small seepage damage range, drilling obliquely through drainage grouting conduits Hole insertion or oblique jacking into the seepage damage area for treatment; in the case of a large seepage damage range, the vertical drilling and insertion or jacking of the seepage damage area through the drainage drainage positioning grouting conduit is carried out for rapid treatment, and then the drainage is injected into the damage area. The slurry pipe is drilled obliquely or inserted obliquely into the seepage damage area for consolidation and treatment. The invention treats the seepage damage of groundwater in the foundation pit project according to the situation, realizes high-efficiency treatment, and saves construction cost and construction period.

The three-dimensional comprehensive, high-efficiency and precise control technology method for coal-gas coexisting mines disclosed by the invention includes the following steps: S10, calculating coal seam gas geological reserves and surrounding rock oil and gas geological reserves; S20, establishing a reasonable parameter model for drilling arrangement; S30: constructing in the coal seam Directional long drilling along the coal seam, and staged hydraulic fracturing construction; S40: Through the monitoring of the extraction data, combined with parameters such as the extraction period, comprehensively evaluate the treatment effect, and provide a design basis for the treatment area under similar geological conditions. Formed a multi-dimensional three-dimensional surrounding rock oil and gas-coal seam gas comprehensive drainage prevention technology for coal and gas coexisting mine disasters, realizing spatial and temporal three-dimensional drainage of gas dynamics in mining space disasters, improving mine mining and gas drainage efficiency, and fundamentally to solve the problem of mine gas disasters.
