【摘要】：礦井工作面底板突水一直是影響煤礦安全生產(chǎn)的重要因素之一,合理有效的探查底板隱伏構(gòu)造及富水性是煤礦防治水措施制定的關(guān)鍵。論文以陽泉新景礦80111工作面為研究對(duì)象,采用綜合物探手段對(duì)工作面附近的富水情況進(jìn)行了研究分析,為煤礦防治水措施的制定提供了科學(xué)依據(jù)。論文在考慮電法勘探中的音頻電透視具有橫向上異常位置定位精確,礦井直流電法對(duì)縱向上的異常分布特征響應(yīng)明顯的特點(diǎn)基礎(chǔ)上,采用綜合物探手段對(duì)研究區(qū)底板巖層附近的水文地質(zhì)條件予以探查。在對(duì)原始資料處理分析的基礎(chǔ)上繪制了相關(guān)物探圖件,根據(jù)煤層底板視電阻率等值線圖,對(duì)兩種物探成果分別圈定異常區(qū),再結(jié)合地質(zhì)資料解譯出沿物探測(cè)線方向上的電性變化特征。最后通過兩種方法探測(cè)結(jié)果的對(duì)比分析,圈定了 80111工作面底板富水情況。探測(cè)結(jié)果表明,礦井音頻電透及直流電法各探測(cè)3處異常區(qū),對(duì)比橫、縱向探測(cè)的異常位置及范圍,再結(jié)合已有的地質(zhì)資料,對(duì)探測(cè)的3個(gè)異常區(qū)的位置及范圍進(jìn)行了校正。本文的研究認(rèn)為音頻電透視法與礦井直流電法雖都能夠有效探測(cè)工作面底板的富水性,但單一的物探方法均不僅具有多解性,且單一的剖面或斷面上難以準(zhǔn)確圈定異常區(qū)范圍,而綜合物探可以提高地球物理資料解釋的準(zhǔn)確性。
[Abstract]:The water inrush from the floor of mine face is always one of the important factors that affect the safety of coal mine production. Reasonable and effective exploration of the hidden structure of floor and water enrichment is the key to the formulation of water prevention measures in coal mine. This paper takes 80111 face of Yangquan Xinjing Mine as the research object. This paper studies and analyzes the situation of water enrichment near the coal face by means of comprehensive geophysical exploration, which provides a scientific basis for the formulation of water prevention measures in coal mines. On the basis of the obvious response of mine direct current method to the characteristic of longitudinal anomalous distribution, The hydrogeological conditions near the floor strata in the study area are probed by means of comprehensive geophysical prospecting. Based on the processing and analysis of the original data, the relevant geophysical maps are drawn, and the contour map of apparent resistivity of the coal seam floor is drawn according to the contour map of the apparent resistivity of the coal seam floor. The two geophysical exploration results are used to delineate the anomalous areas respectively, and the electrical variation characteristics along the object detection line are interpreted by combining the geological data. Finally, the comparison and analysis of the detection results by the two methods are carried out. The water enrichment in the floor of 80111 working face is delineated. The detection results show that the abnormal position and range of the horizontal and longitudinal detection are compared with the three abnormal areas detected by the audio permeation method and the direct current method respectively, and combined with the existing geological data. The location and range of the three anomalous areas detected are corrected. In this paper, it is considered that both the audio frequency electric perspective method and the mine direct current method can effectively detect the water enrichment of the bottom plate of the working face, but the single geophysical prospecting method is not only multi-solvable. It is difficult to accurately delineate the anomalous area on a single section or section, and comprehensive geophysical exploration can improve the accuracy of geophysical interpretation.
