田陈煤矿3下7110综放工作面煤层埋藏深、厚度大、地质构造复杂、不规则布置、开采条件复杂,顶板具有强冲击倾向性,冲击地压威胁大,特别是工作面机尾段在轨道巷里段向采空区推进,回采方案的选择将直接决定该区域的冲击危险程度及矿压显现程度。该文主要介绍了该综放工作面向采空区推进方案的选择。
田陳煤礦3下7110綜放工作麵煤層埋藏深、厚度大、地質構造複雜、不規則佈置、開採條件複雜,頂闆具有彊遲擊傾嚮性,遲擊地壓威脅大,特彆是工作麵機尾段在軌道巷裏段嚮採空區推進,迴採方案的選擇將直接決定該區域的遲擊危險程度及礦壓顯現程度。該文主要介紹瞭該綜放工作麵嚮採空區推進方案的選擇。
전진매광3하7110종방공작면매층매장심、후도대、지질구조복잡、불규칙포치、개채조건복잡,정판구유강충격경향성,충격지압위협대,특별시공작면궤미단재궤도항리단향채공구추진,회채방안적선택장직접결정해구역적충격위험정도급광압현현정도。해문주요개소료해종방공작면향채공구추진방안적선택。
The 7110 full-mechanized top-caving mining face thick seam with a higher degree, complex geological conditions, layout irregular, complicated mining conditions and strong rock-burst roof in Tianchen coal mine is threatened by rock burst, Especially in the scraper conveyer rear, working face mined forward the goaf, The mining scheme directly determines the rock-burst and mine pressure behavior of this area. This paper presents the choice of mining scheme about The full-mechanized top-caving mining forward goaf.
