The technical regulations for mining paste filling are a complex system involving multiple aspects and links. The following is an overview of the relevant technical regulations based on publicly released information:

1、 Overview of paste filling technology
Paste filling technology is a coal mining technique that processes solid waste such as coal gangue, fly ash, and industrial slag generated during coal mine production into slurry filling materials on the ground. The filling materials are pressurized by a dedicated filling pump and transported to the underground working face through filling pipelines to control the movement of overlying rock layers and surface deformation.

2、 Composition of paste filling material
The paste filling material is mainly composed of binders, aggregates, chemical additives, and other materials. Among them, the binder is made up of cement, gypsum, and various additives, while the aggregate includes coal gangue, fly ash, inferior soil, urban solid waste, etc. Chemical additives are used to improve the performance of the filling material.

3、 Process flow of paste filling
The paste filling process mainly includes the following steps:

Material preparation: Crush and screen aggregates such as coal gangue and fly ash to ensure that the particle size meets the requirements.
Mixing ratio: Mix and stir materials such as aggregates, binders, and water in proportion to make a paste slurry.
Pipeline pumping: The mixed paste slurry is pressurized by a filling pump and transported through pipelines to the underground filling working face.
Filling body construction: Fill the working face underground using hydraulic filling supports and auxiliary isolation measures to form a closed goaf space for filling.
4、 Key points of technical regulations for paste filling
System layout: The paste filling system should be arranged reasonably, including filling stations, pipelines, working face filling subsystems, etc., to ensure that the filling materials can be smoothly transported to the filling site.
Equipment requirements: Filling pumps, pipelines, mixers, and other equipment should meet the technical requirements for paste filling to ensure filling efficiency and quality.
Proportion control: The proportion of paste filling materials should be strictly controlled to ensure the strength and stability of the filling body.
Filling sequence: The filling sequence is generally carried out from the low end to the high end of the working face, or can be determined according to the actual situation on site.
Safety monitoring: During the filling process, it is necessary to strengthen the monitoring and maintenance of equipment such as filling pipelines and filling supports to ensure the safety of filling.
Environmental protection: Paste filling technology should meet the requirements of green mining and reduce its impact on the environment.
5、 Example of paste filling technology
Taking Taiping Coal Mine of Jining Mining Group as an example, the mine adopts paste filling technology to solve the problems of coal pressure in villages and increase the mining limit. By establishing a filling station on the ground, Sihe River sand, power plant fly ash, binder, and water are prepared into a paste filling slurry, which is then transported to the underground coal mining face for filling through filling pumps and pipelines.

In summary, the technical regulations for mining paste filling are a complex system involving multiple aspects and links, which requires strict operation and management in accordance with the technical regulations to ensure the filling effect and safe production.
