An inclined layered solid-filling mining method in an ultrathick coal layer is applicable to exploitation in a "three-unders" ultrathick coal layer. In this method, the number of inclined layers is determined based on a principle of layered thickness from 2.5 m to 4.5 m, and a layered-exploitation downward-filling exploitation order is adopted. Tunnels and equipment are arranged according to a conventional solid-filling mining method. A cyclic order of mining, layout of metal meshes (14) and bamboo fences (24), and filling is adopted, so as to accomplish filling and exploitation of a first mining face and a first layer (21). Meanwhile, 4 months after the working face of this layer is finished, at a corresponding position in a second layer (22), under the cover of an artificial ceiling formed by the first layer (21), exploitation is performed by using the same filling mining method; such a cycle is repeated, and exploitation in a current layer is performed under the cover of an artificial ...

Multi-sensor-based fusion target scoring method, storage medium and equipment

Номер: CN116026190A
Автор: GUO YAN, YU DIANCHUN, GUO JIWEI, LI HE
Принадлежит:

The invention relates to a target scoring method based on multi-sensor fusion, a storage medium and equipment. The target scoring method is used for achieving multi-sensor fusion processing and positioning of newly-added bullet point target scoring in the outdoor live ammunition shooting process. The multi-sensor fusion target scoring equipment comprises a sound image sensor, a far infrared image sensor, a near infrared image sensor and a processing program module. Before live ammunition shooting, the far infrared module identifies the target plate and positions the four edges and the four corners of the target sheet through the temperature difference of all the areas; the near-infrared module positions the four edges and the four corners of the target sheet through the brightness difference between the target sheet and the target plate. During live ammunition shooting, the reliability of near-infrared image processing and identification of ammunition points is improved through a method ...
