【摘要】：隨著煤炭?jī)r(jià)格的變動(dòng)，使國(guó)內(nèi)外的部分礦山實(shí)施了井工轉(zhuǎn)露天開(kāi)采。而原有井工礦所遺留的大量形態(tài)各異、成因復(fù)雜的采空區(qū)困擾著諸多礦山，如何圈定出其影響區(qū)域及采空區(qū)深度已成為重要課題。 本文針對(duì)采空區(qū)范圍、深度探測(cè)問(wèn)題以鄂爾多斯市烏蘭煤炭集團(tuán)公司特拉布拉煤礦為研究對(duì)象運(yùn)用瞬變電磁探測(cè)技術(shù)，通過(guò)對(duì)范圍明確的采空區(qū)的上賦巖層施加不同重量礦用卡車等大型礦用機(jī)械設(shè)備，，確定研究區(qū)域內(nèi)上賦巖層所能承受的重量極限值。研究?jī)?nèi)容具體分為以下方面： （1）通過(guò)對(duì)礦區(qū)的現(xiàn)場(chǎng)調(diào)研，確定實(shí)驗(yàn)區(qū)域范圍，運(yùn)用GPS-RTK放樣拐點(diǎn)坐標(biāo)。 （2）在確定的實(shí)驗(yàn)區(qū)域運(yùn)用ATEM-10KW瞬變電磁發(fā)射機(jī)和ATEM-IV型瞬變電磁接收機(jī)，使用重疊回線法進(jìn)行采空區(qū)探測(cè)工作。 （3）分別運(yùn)用Grapher4.0、ATEM-2pro、Voxler3、Surfer8等軟件針對(duì)探測(cè)結(jié)果進(jìn)行分析，最得出視電阻率等值線圖以及地下采空區(qū)三維位置示意圖。 （4）針對(duì)三維位置示意圖，運(yùn)用FLAC-3D軟件建立采空區(qū)模型，并選定6個(gè)巖土介質(zhì)破壞嚴(yán)重且地下應(yīng)力環(huán)境復(fù)雜的地表薄弱位置施加相當(dāng)于不同噸位的礦用開(kāi)車重量的面向載荷，計(jì)算出各位置的極限承重，最終得出地表最薄弱位置所能承受的最大礦用機(jī)械設(shè)備的重量為248t。 本文針對(duì)運(yùn)用瞬變電磁法圈定出的空間位置、形態(tài)、厚度已明確的采空區(qū)，對(duì)其上賦巖層施加不同重量礦用卡車等大型礦用機(jī)械設(shè)備，分析其極限承重能力，對(duì)特拉布拉煤礦甚至其他地質(zhì)條件相似的擁有采空區(qū)安全隱患的礦山具有重要的現(xiàn)實(shí)和長(zhǎng)遠(yuǎn)意義。
[Abstract]:With the change of coal price, some mines at home and abroad have been converted to open-pit mining. However, a large number of different shapes have been left over from the original wells and mines, and many mines have been troubled by the complex goaf of origin. How to delineate the affected area and the depth of the goaf has become an important subject. Aiming at the scope of goaf and depth detection problem, this paper applies transient electromagnetic detection technology to the Trabra Coal Mine of Wu Lan Coal Group Company of Ordos City. By applying large mining machinery and equipment such as truck with different weights to the upper strata of the goaf, the limit value of the weight of the upper strata in the study area can be determined. The research contents are divided into the following aspects: (1) through the field investigation of the mining area, determine the scope of the experimental area, GPS-RTK inflection point coordinates are used. (2) ATEM-10KW transient electromagnetic transmitter and ATEM-IV transient electromagnetic receiver are used in the determined experimental area. The overlapped loop method is used to detect the goaf. (3) the detection results are analyzed by using the software of Grapher 4.0 / ATEM-2proVoxler3 / Surfer8 respectively. The contour map of apparent resistivity and 3D position map of underground goaf are obtained. (4) the model of goaf is established by using FLAC-3D software. At the same time, six weak positions of ground surface with serious damage of rock and soil medium and complicated underground stress environment are selected to apply the face load equivalent to mine starting weight of different tonnage, and the ultimate bearing capacity of each position is calculated. Finally, it is concluded that the maximum weight of mining machinery and equipment can be supported by the weakest position of the earth's surface is 248 t. In this paper, aiming at the goaf defined by transient electromagnetic method in which the space position, shape and thickness have been determined, large mining machinery equipment such as mine truck with different weights is applied to its upper strata, and its ultimate load-bearing capacity is analyzed. It has important practical and long-term significance for Trabra coal mine and other mines with similar geological conditions.
