【摘要】：畢節(jié)市煤炭資源豐富,煤種齊全,煤質(zhì)優(yōu)良,是全國重要的無煙煤生產(chǎn)基地和煤電產(chǎn)業(yè)基地。根據(jù)市場經(jīng)濟(jì)發(fā)展新形勢,科學(xué)辦礦,積極推廣采掘機(jī)械化程度,依靠科技進(jìn)步提升煤礦產(chǎn)能,降低生產(chǎn)成本,提高煤炭企業(yè)的經(jīng)濟(jì)效益,是做大做強(qiáng)煤礦企業(yè)的必然選擇。富祥煤礦位于織納煤田,井田面積小、可采煤層數(shù)多、煤質(zhì)較好、地質(zhì)構(gòu)造復(fù)雜,特別織納煤田是國家劃定的煤與瓦斯突出礦區(qū),煤層瓦斯含量較高。本文根據(jù)富祥煤礦的開采現(xiàn)狀,對富祥煤礦開拓開采、水平及采區(qū)劃分優(yōu)化的原因做出了分析,并緊緊圍繞礦井的基本特點,合理確定開拓部署,對首采區(qū)的井下開采、運輸進(jìn)行了重新設(shè)計,確保資源的合理開采。同時本文結(jié)合國內(nèi)外煤礦開拓開采發(fā)展現(xiàn)狀,積極采用國內(nèi)外先進(jìn)成熟的技術(shù)裝備和先進(jìn)的生產(chǎn)工藝,因地制宜地提高機(jī)械化程度,建設(shè)高產(chǎn)高效的現(xiàn)代化礦井。在通風(fēng)與安全方面,本文根據(jù)瓦斯賦存狀況計算了礦井的一采區(qū)的瓦斯資源儲量,提出了瓦斯抽采方法,同時結(jié)合開拓系統(tǒng),對富祥煤礦礦井主要危害因素及危害程度進(jìn)行了分析,提出了主要災(zāi)害防治措施。在“六大系統(tǒng)”設(shè)計方面,依據(jù)富祥煤礦的開拓開采布局,結(jié)合國家對“六大系統(tǒng)”建設(shè)相關(guān)文件的要求,對礦井的“六大系統(tǒng)”進(jìn)行優(yōu)化,確定了合理的井下安全避險系統(tǒng)。最后針對富祥煤礦的建設(shè)規(guī)劃,對項目的投資進(jìn)行估算,分析了項目的經(jīng)濟(jì)效益和項目投資存在的風(fēng)險,提出了風(fēng)險防范措施,評價了項目產(chǎn)生的社會效益。
[Abstract]:Bijie City is rich in coal resources, complete in coal types and excellent in coal quality. It is an important anthracite production base and coal power industry base throughout the country. According to the new situation of market economy development, we should scientifically run mines and actively promote the degree of mechanization of mining. Depending on the progress of science and technology to improve coal production capacity, reduce production costs, and improve the economic benefits of coal enterprises, it is an inevitable choice for coal mining enterprises to become bigger and stronger. Fuxiang Coal Mine is located in Zhina Coal Field, with a small area, a large number of mineable coal seams, and better coal quality. The geological structure is complicated, especially Zhina coalfield is the coal and gas outburst mine designated by the state, and the coal seam gas content is relatively high. According to the present mining situation of Fuxiang coal mine, this paper develops and exploits Fuxiang coal mine. The reasons for the optimization of the level and the division of the mining area are analyzed, and the rational development and deployment are determined around the basic characteristics of the mine, and the underground mining and transportation of the first mining area are redesigned. At the same time, according to the present situation of development and development of coal mines at home and abroad, this paper actively adopts advanced and mature technical equipment and advanced production technology at home and abroad to improve the degree of mechanization according to local conditions. In the aspect of ventilation and safety, according to the situation of gas occurrence, this paper calculates the gas resource reserves in the first mining area of the mine, puts forward the method of gas extraction, and combines with the development system, This paper analyzes the main harm factors and harm degree of Fuxiang coal mine, and puts forward the main disaster prevention measures. In the design of "six systems", according to the development and mining layout of Fuxiang coal mine, According to the requirements of the state for the construction of the "six major systems", the "six major systems" of the mine are optimized, and a reasonable underground safety and risk avoidance system is determined. Finally, the investment of the project is estimated according to the construction plan of Fuxiang coal mine. This paper analyzes the economic benefits of the project and the risks existing in the project investment, puts forward the risk prevention measures, and evaluates the social benefits of the project.
