It is an underground mining technology that does not need to build a tailings pool. It counts the total tailings data produced in the mining area and the remaining tailings data after filling the goaf; plans and selects sand within the preset range of the mining area. Aggregate yard, the empty area formed meets the storage requirements for the remaining tailings; ore and waste rock are mined in the mining area, and the ore is sorted to produce concentrate and tailings; the waste rock and beneficiation produced by mining The produced waste rocks are crushed, and the crushed materials are screened according to the preset size to form sand and gravel aggregates and screening residues; the tailings or screening residues are filled into the goaf. After the ore and waste rock are mined, a goaf containing the tailings is formed. The volume of the goaf meets the storage requirements for the tailings produced by ore sorting and the required cementing materials. A sufficient empty area is formed to fill the tailings produced after mineral processing into the underground, and there is no tailings pond on the surface, which truly realizes a "tailing-free mine". Sand and gravel aggregates can also be sold, which is conducive to environmental protection and national economic construction.

The region intercepting circuit for digital video image consists of data memory unit, address generating unit, address control unit and other parts. The data memory unit stores the digital video signal of the required part and outputs images of the intercepted region, and in controlled by address control unit controlled address generating unit. The present invention has the advantages of correct timing, convenient regulation and low cost owing to that EPROM is used in generating intercepting control signal. The present invention has also the advantages of faster response speed than software method and this results in real-time property and clear and vivid dynamic image effect. Compared with other hardware method, the present invention has cheap common elements and devices used and simple and clear circuit. The present invention may be used widely in display circuit of various formats and sizes.

The invention relates to the field of mathematics education, and particularly relates to an addition and subtraction question answering device for mathematics education. The invention aims to solve atechnical problem of providing an addition and subtraction question answering device for mathematics education which can conduct a question answering competition to enable students be high in learningenthusiasm and is high in interestingness. The technical scheme is that the addition and subtraction question answering device for mathematics education comprises a box body and the like, wherein thefront side of the box body is provided with a box cover, the box cover is provided with two openings, the middle part of the front side of the box cover is engraved with '+', the right of the front side of the box cover is sequentially engraved with '=' and a question mark, the box body is internally provided with a rotating device, the middle part of the front side of the box cover is provided with an adjusting device, and the adjusting device is located between the two openings. The addition and subtraction question answering device for mathematics education adjusts Arabic numerals in the openings through the rotation of the rotating device and adjusts the plus or minus sign through the adjusting device, thereby enabling the students to perform question answering according to the observed Arabic numerals. The addition and subtraction question answering device for mathematics education can randomly select a group for question answering through a group selecting device, thereby enabling the competitiveness to be higher, and being more interesting.

The invention provides a human molecular modified insecticidal protein and its preparation method and application, belonging to the field of genetic engineering and biological control. The present invention provides a human molecularly modified insecticidal protein, the amino acid sequence of the insecticidal protein CCL-CCL_scFv is shown in SEQ ID No.1. The insecticidal protein CCL-CCl_scFv has a significantly higher affinity to the midgut BBMV of diamondback moth (Plutella xylostella) than Cry1Ab toxin, and competes with Cry1Ab and Cry1Ac toxin for binding to midgut BBMV of diamondback moth, and is a mimic of Cry1Ab and Cry1Ac toxin; The indoor insecticidal biological activity of Plutella xylostella was measured, and the 3d lethality rate can reach 55.35%, which can effectively replace Cry1Ac toxin for biological control of insect pests.
