【摘要】：工作面實(shí)現(xiàn)高產(chǎn)高效是現(xiàn)代化礦井重要關(guān)注的問題之一,而實(shí)現(xiàn)高產(chǎn)高效的較為有效的方式即是增加工作面的采高、傾斜長度和推進(jìn)長度。工作面的采高和推進(jìn)長度一般受礦井煤層地質(zhì)賦存條件等因素的影響。因此逐漸擴(kuò)展工作面長度成為各個(gè)礦區(qū)近年來主要研究的技術(shù)方向之一。工作面長度增加不僅可以大大提升工作面產(chǎn)能,避免開采浪費(fèi),而且面長加長后同時(shí)可以減少巷道布置,從而減少工作面搬家次數(shù),這樣更加利于礦井的集中高效生產(chǎn),提高資源生產(chǎn)效率。晉煤集團(tuán)趙莊煤礦為了提高產(chǎn)能,目前將工作面長度已經(jīng)增加到了295m。工作面不斷加長的同時(shí),在開采過程當(dāng)中的一些礦壓顯現(xiàn)也逐漸出現(xiàn)了一系列新的特征,比如來壓強(qiáng)度大、來壓持續(xù)過程延長、煤壁片幫加重、漏矸頻發(fā),經(jīng)常出現(xiàn)一些露矸冒頂?shù)氖鹿?這樣不利于礦井的安全生產(chǎn),同時(shí)減緩了資源開采進(jìn)度。因此,為更好的掌握工作面加長之后的礦壓顯現(xiàn)特點(diǎn),以及工作面加長以后為礦井生產(chǎn)帶來的一些隱性災(zāi)害,開展大采高加長工作面的礦壓顯現(xiàn)特征研究,就顯得十分必要。本文以趙莊煤礦五盤區(qū)首個(gè)加長工作面5316為工程背景,采用力學(xué)理論分析,現(xiàn)場實(shí)測和數(shù)學(xué)統(tǒng)計(jì)分析相結(jié)合的方法,主要研究了趙莊煤礦首個(gè)大采高長度為270m的工作面礦壓規(guī)律,并與5302普通長度工作面(斜長為219.7m)的礦壓特征進(jìn)行了對比,得出了工作面長度加長后一些礦壓變化情況,主要研究成果如下:(1)結(jié)合關(guān)鍵層理論,揭示了工作面上覆巖層的關(guān)鍵層分布情況,并通過“板理論”和“梁理論”對加長工作面來壓步距進(jìn)行了理論研究和計(jì)算。通過“板理論”研究了工作面長度對頂板來壓步距以及來壓強(qiáng)度的影響;(2)通過現(xiàn)場實(shí)測的方法,統(tǒng)計(jì)研究了5316大采高加長工作面的礦壓顯現(xiàn)特征;(3)通過現(xiàn)場實(shí)測的方法,對5316加長工作面與5302普通工作面的礦壓顯現(xiàn)特征進(jìn)行了對比分析,掌握了工作面長度加長后礦壓顯現(xiàn)變化情況,驗(yàn)證了理論分析的正確性。(4)通過統(tǒng)計(jì)分析的數(shù)學(xué)方法,分析了工作阻力與初撐力、時(shí)間的相關(guān)關(guān)系,并研究了初撐力和時(shí)間因素對工作阻力的顯著性影響。本論文對趙莊煤礦首個(gè)加長工作面5316的礦壓顯現(xiàn)特征進(jìn)行了詳細(xì)的研究,揭示了工作面加長之后的相關(guān)礦壓顯現(xiàn)特征,并對比了與普通工作面的礦壓情況,一定程度上不僅為趙莊煤礦加長工作面的安全生產(chǎn)提供了指導(dǎo),也為類似地質(zhì)條件的工作面提供了礦壓顯現(xiàn)參考依據(jù),給出了重要的實(shí)際引薦價(jià)值。
[Abstract]:The realization of high yield and high efficiency in working face is one of the most important problems in modern mines, and the more effective way to realize high yield and high efficiency is to increase the mining height, inclined length and propelling length of working face.The mining height and propulsive length of coal face are generally affected by geological conditions of coal seam.Therefore, expanding the working face length gradually becomes one of the main technical research directions in each mining area in recent years.The increase of working face length can not only greatly enhance the productivity of the face and avoid waste of mining, but also reduce the roadway layout after the lengthening of the face length, thus reducing the number of working face moving, which is more conducive to the centralized and efficient production of the mine.Improve the efficiency of resource production.In order to improve production capacity, Zhaozhuang Coal Mine of Jin Coal Group has increased the length of working face to 295 m.As the face continues to grow, a series of new features have gradually emerged during the mining process, such as high pressure intensity, prolonged pressure coming process, heavier coal wall cover, and frequent gangue leakage.There are frequent roof-falling accidents, which is not conducive to the safety of mine production and slow down the progress of resource mining.Therefore, in order to better grasp the characteristics of mine pressure behavior after the face lengthening and some hidden disasters brought to the mine production after the face lengthening, it is very necessary to carry out the study on the characteristics of the mine pressure behavior of the large mining height lengthening working face.In this paper, based on the engineering background of the first extended face 5316 in Wupan District of Zhaozhuang Coal Mine, the method of combining mechanical theory analysis, field measurement and mathematical statistical analysis is adopted.This paper mainly studies the rock pressure law of the first large mining height working face in Zhaozhuang coal mine, and compares it with the mine pressure characteristics of 5302 normal length working face (219.7 m inclined length), and obtains some changes of mine pressure after the length of working face is lengthened.The main research results are as follows: (1) combined with the critical layer theory, the distribution of the key strata of the overlying strata on the face is revealed, and the pressure step distance of the extended working face is theoretically studied and calculated by "plate theory" and "beam theory".The influence of working face length on roof pressure step distance and pressure intensity is studied by means of "plate theory". (2) through the method of field measurement, the characteristics of mine pressure behavior in 5316 large mining height lengthening face are statistically studied.In this paper, the characteristics of mine pressure behavior in 5316 extended face and 5302 common working face are compared and analyzed. The variation of mine pressure behavior after the length of working face is increased is grasped, and the correctness of the theoretical analysis is verified. 4) the mathematical method of statistical analysis is used to verify the correctness of the theoretical analysis.The relationship between the working resistance and the initial support force and time was analyzed, and the significant influence of the first support force and time factor on the working resistance was studied.In this paper, the characteristics of mine pressure behavior of the first extended face 5316 in Zhaozhuang coal mine are studied in detail, and the related characteristics of mine pressure behavior after the face lengthening are revealed, and the mine pressure situation of the coal face is compared with that of the common working face.To a certain extent, it not only provides the guidance for the safety production of the extended working face in Zhaozhuang Coal Mine, but also provides the reference basis for the appearance of mine pressure in the face of similar geological conditions, and gives the important practical introduction value.
