The present application belongs to the field of coal mine roadway construction, and particularly relates to a method for self-forming a roadway by top cutting at a negative angle. The method comprises the following steps: drilling a field in front of a working face and close to a right side of a mining roadway; drilling anchor holes and top cutting holes along a strike and staggered construction, and installing grouting anchor cables in the field; cutting the basic roof and the immediate roof at a negative angle through the top cutting holes at the back of the working face, constructing a roadway-side gangue retaining structure, grouting through the grouting anchor cables and anchoring the grouting anchor cables on the roadway-side gangue retaining structure; and monitoring the deformation of the steel mesh at the grouting anchor cable and adjusting through a nut. The present application can ensure that the construction position of the roadway-side gangue retaining structure does not affect the width of the self-supporting roadway and the integrity of the roof by constructing a field of a certain width in advance. The negative angle top cutting holes can cut a section that is deviated to the direction of the goaf, so that the gangue formed by the collapse of the immediate roof moves to the direction of the goaf and does not move to the mining roadway in large quantities, thereby ensuring the safety of the construction in the mining roadway.

This invention provides a high-efficiency dust suppression device for indoor construction, relating to the field of construction dust suppression technology. It includes: a main body with a guide groove on its front end; a rotating shaft is mounted inside the guide groove via a bearing; an inclined baffle is fixedly mounted on the outer circumference of the rotating shaft; and a horizontal baffle is fixedly mounted on the top of the inclined baffle. This invention, in conjunction with a pre-run monitoring and timing module, a pre-run confirmation timing module, and a microcontroller, forms an intelligent locking and control system.

This invention belongs to the field of building materials technology, specifically disclosing a sound-absorbing porous foamed concrete composite board and its preparation method. Using foamed concrete as the substrate of the composite board effectively solves the problem of poor environmental performance of traditional sound insulation materials. Compared with materials such as polystyrene and sound-absorbing rock wool, it does not require a large amount of energy for preparation and can utilize recycled raw materials. It does not produce toxic powder after aging, reducing harm to the air environment and human health, while also avoiding the flammability hazards of traditional materials. The closed-cell sound insulation layer's sealed pores can block direct sound wave penetration, achieving basic sound insulation. The sound-absorbing pores of the porous sound-absorbing layer, combined with the interconnected channels, introduce incident sound waves into the interior. Energy is dissipated through reflection and friction within the channels, forming a dual protection of "sound absorption and sound insulation." This solves the core problem of poor sound insulation performance of traditional concrete and compensates for the short lifespan of traditional sound insulation materials, extending the overall service life of the board.
