Technical specification for mining paste filling in coal mines1 ScopeThis document specifies the applicable conditions, system layout, composition of filling and mining equipment, process requirements, surface deformation and Underground mine pressure monitoring and other requirements. This document is applicable to improving the recovery rate of coal resources, the safe mining of "three downs and one up" coal pressing, and the recovery of room-and-pillar, strip and other legacy coal resources. Source mining, ecological protection of mining areas; harmless treatment of solid wastes such as coal mine gangue reduction and construction waste.2 Normative referencesThe contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, dated citations documents, only the version corresponding to that date applies to this document; for undated references, the latest edition (including all amendments) applies to this document. JB/T 13439-2018 Mine Piston Filling Pumping Machine3 Terms and DefinitionsThe following terms and definitions apply to this document. 3.1 pastefillingmaterial Materials such as coal gangue, fly ash, slag, harmless construction waste, aeolian sand, river sand, loess, tailings and other materials that will be broken during paste filling mining It is a composite material that is mixed with cementitious material and water (may contain additives or admixtures) in an appropriate proportion, uniformly stirred and then filled into the goaf. 3.2 Paste backfill mining pastebackfilmining A coal mining technology that fills the paste filling material into the goaf to control the movement of the overlying strata. 3.3 It can realize the working face required by the cooperative operation of coal mining and paste filling. 3.4 Hydraulic support that can realize the cooperative operation requirements of coal mining and paste filling. 3.5 The filling paste is made by crushing or screening solid wastes such as coal gangue, slag, harmless construction waste or other aggregates. A system for aggregate grading requirements. 3.6 A system that measures, transports and stirs paste filling aggregates, cementitious materials, additives and water in proportion to make paste filling materials. ...... |
