【摘要】：礦井在生產(chǎn)過(guò)程中，回采工作面的開(kāi)采或者巷道掘進(jìn)時(shí)會(huì)對(duì)上覆巖層造成采動(dòng)擾動(dòng)，這種擾動(dòng)會(huì)使煤或者巖體本來(lái)就在高應(yīng)力集中的狀態(tài)下，又積聚了大量的彈性勢(shì)能。當(dāng)煤或巖體的彈性勢(shì)能突然釋放時(shí)就會(huì)造成煤或巖體的突然冒落、拋出，產(chǎn)生震動(dòng)、聲響、氣浪等明顯的礦震現(xiàn)象，這些現(xiàn)象便統(tǒng)稱為煤礦的動(dòng)壓現(xiàn)象，亦為強(qiáng)礦壓顯現(xiàn)。強(qiáng)礦壓的突然顯現(xiàn)會(huì)對(duì)礦井的人員和設(shè)備造成巨大的損害，其危害如同具有相當(dāng)能量的炸藥發(fā)生的爆炸現(xiàn)象，有的甚至能形成強(qiáng)烈的暴風(fēng)。同時(shí)礦井在開(kāi)采的過(guò)程中，如果一直處于高應(yīng)力集中的狀態(tài)之下，沖擊地壓發(fā)生的幾率會(huì)大大增加。 陜西胡家河煤礦由于設(shè)計(jì)之初就屬于深部開(kāi)采，井田主要可采煤層為4號(hào)煤層，3號(hào)煤為局部可采煤層，煤層埋深為578～817m，平均680m，因此礦井的大采深就以決定了其礦壓顯現(xiàn)的問(wèn)題尤為嚴(yán)重。本輪為針對(duì)胡家河煤礦401102、401103工作面強(qiáng)礦壓現(xiàn)象所造成的危害，先期進(jìn)行了詳細(xì)的礦井水文地質(zhì)調(diào)研，后進(jìn)行有針對(duì)的分析。分別對(duì)開(kāi)采深度、煤層沖擊傾向、煤層厚度、煤柱的影響、頂板巖性等方面進(jìn)行了詳細(xì)的分析與計(jì)算，完成了對(duì)工作面掘進(jìn)過(guò)程中的強(qiáng)礦壓危險(xiǎn)性評(píng)價(jià)，并對(duì)后期工作面開(kāi)采過(guò)程中的危險(xiǎn)性進(jìn)行了評(píng)價(jià)。提出了合理的卸壓措施。最后針對(duì)胡家河礦自身的條件，制定了一套有針對(duì)性的強(qiáng)礦壓多維信息監(jiān)測(cè)系統(tǒng)和防護(hù)措施。
[Abstract]:In the process of mine production, the mining of mining face or roadway excavation will cause mining disturbance to the overlying strata, which will make coal or rock mass accumulate a large amount of elastic potential energy under the condition of high stress concentration. When the elastic potential energy of coal or rock mass is suddenly released, it will cause coal or rock mass to suddenly fall, throw out, produce vibration, sound, air wave and other obvious phenomena of mine shock. These phenomena are called dynamic pressure phenomenon of coal mine, and it is also known as strong rock pressure phenomenon. The sudden appearance of strong mine pressure will cause great damage to the personnel and equipment of the mine, and its harm is like the explosion phenomenon of explosive with considerable energy, some of which can even form a strong storm. At the same time, in the process of mining, if the mine is always under the condition of high stress concentration, the probability of rock burst will be greatly increased. The Hujiahe Coal Mine in Shaanxi Province belongs to deep mining since the beginning of its design. The main mineable coal seam in the mine field is No. 4 coal seam, the No. 3 coal seam is local mining coal seam, and the coal seam burying depth is 578 ~ 817m, with an average of 680m, so the problem that the mine's large mining depth determines the appearance of mine pressure is especially serious. In view of the harm caused by the phenomenon of strong mine pressure in Hujiahe Coal Mine 401102 and 401103, the detailed mine hydrogeological investigation was carried out in advance, and then the analysis was carried out. The mining depth, coal seam impact tendency, coal seam thickness, the influence of coal pillar, roof lithology and so on are analyzed and calculated in detail. And the risk of mining process in the later mining face was evaluated. Reasonable pressure relief measures are put forward. Finally, according to the conditions of Hujiahe Mine, a set of multi-dimensional information monitoring system and protective measures for strong mine pressure are established.
