【摘要】：在進(jìn)行邊采邊復(fù)規(guī)劃設(shè)計過程中,實地復(fù)墾施工時耕地區(qū)應(yīng)當(dāng)采取的施工標(biāo)高,關(guān)系到整個復(fù)墾工程的成敗,尤為重要。因此為了更好的指導(dǎo)復(fù)墾工程實地施工,以邊采邊復(fù)技術(shù)思想為指導(dǎo),首先系統(tǒng)分析了影響耕地動態(tài)施工標(biāo)高的三大因素,在此基礎(chǔ)上構(gòu)建了耕地動態(tài)施工標(biāo)高的理論模型。并結(jié)合動態(tài)沉陷模型和概率積分法,根據(jù)單一煤層和多煤層不同開采條件下地面沉陷特點,分別推導(dǎo)出了單一煤層和多煤層不同開采條件下,耕地動態(tài)施工標(biāo)高的數(shù)學(xué)模型。最后以安徽某高潛水位煤礦為實例,分別對兩個不同復(fù)墾施工時刻,耕地區(qū)A1,A2點的施工標(biāo)高進(jìn)行模擬分析計算,當(dāng)復(fù)墾施工時刻t_(s1)=210 d時,兩點的施工標(biāo)高分別為23.6,24.2 m,t_(s2)=296 d時兩點的施工標(biāo)高分別為22.9,23.7 m,結(jié)果表明耕地動態(tài)施工標(biāo)高模型具有很好的適用性,這將促進(jìn)邊采邊復(fù)技術(shù)的推廣應(yīng)用。
[Abstract]:In the process of planning and designing while mining and reclaiming, the construction elevation that should be adopted in the field reclamation construction is of great importance to the success or failure of the whole reclamation project. Therefore, in order to better guide the field construction of reclamation project, with the idea of side mining and recovery technology as the guidance, this paper first systematically analyzes the three major factors that affect the dynamic construction elevation of cultivated land, and on this basis, constructs the theoretical model of the dynamic construction elevation of cultivated land. Combined with dynamic subsidence model and probabilistic integration method, according to the characteristics of surface subsidence under different mining conditions of single coal seam and multiple coal seam, the mathematical model of dynamic construction elevation of cultivated land under different mining conditions of single coal seam and multiple coal seam is derived respectively. Finally, taking a coal mine with a high diving level in Anhui Province as an example, the construction elevation of A _ (1) A _ (2) point in ploughing area is simulated and calculated at two different reclamation construction times. When the reclamation construction time is t_(s1)=210 d, The construction elevation of two points is 23.6m / 24.2 m / d / s / 296d respectively. The results show that the dynamic construction elevation model of cultivated land has a good applicability, which will promote the popularization and application of the technology of side mining and recovery.
