【摘要】：礦井通風系統(tǒng)計算與模擬是對礦井通風系統(tǒng)進行理論分析,找出問題、做出評價,進而提出解決辦法和改進措施；對提高礦井的生產(chǎn)安全狀況有非常重要的意義。MIVENA是一款可以讓通風工程師和研究者在礦井的動態(tài)生產(chǎn)過程中對礦井的風流、氣候、溫度和濕度狀況進行解算和分析的礦井通風模擬系統(tǒng)[1]。在通風系統(tǒng)中的風流狀態(tài)模擬、風量調(diào)節(jié)預測、井下氣候環(huán)境預測等方面都具有很高的實用價值。MIVENA系統(tǒng)在通風安全理論基礎(chǔ)之上,建立了模擬預測模型,進而以計算機為工具立足解決實際的礦井通風問題。本文以隸屬于阜新礦業(yè)集團的興阜煤礦為實例,以現(xiàn)場實測數(shù)據(jù)為基礎(chǔ),運用MIVENA系統(tǒng)進行精確模擬,解算出原孫家灣系統(tǒng)通風阻力占總阻力的21%,并解算出興阜煤礦通風系統(tǒng)中的大風阻分支,主要位于新副井、-400總排風道、-340大巷及二、三皮帶道等巷道,在通風網(wǎng)絡解算分析的基礎(chǔ)上對興阜煤礦部分巷道實施示蹤氣體實驗,建立了示蹤氣體濃度擴散數(shù)學模型并化簡求解,通過對實驗結(jié)果與模擬計算結(jié)果對比分析,診斷出興阜煤礦的重點漏風區(qū)域。針對以上三方面問題,分別從降阻調(diào)節(jié)、封堵漏風及簡化孫家灣生產(chǎn)系統(tǒng)三方面入手,對興阜煤礦通風系統(tǒng)進行優(yōu)化改造,通過MIVENA系統(tǒng)對優(yōu)化后的通風系統(tǒng)解算,興阜煤礦通風系統(tǒng)較優(yōu)化前總風量增加約10%,風壓降低約25%,增加了該礦井的經(jīng)濟效益。
[Abstract]:The calculation and simulation of mine ventilation system is to carry on the theoretical analysis to mine ventilation system, find out the problem, make the evaluation, and then put forward the solution and the improvement measure; It is very important to improve mine production safety. Mivena is a kind of ventilation engineers and researchers in the mine dynamic production process of the mine air flow, climate, Mine ventilation simulation system for calculation and analysis of temperature and humidity conditions [1]. Mivena system has high practical value in air flow state simulation, air flow regulation prediction, downhole climate and environment prediction and so on. On the basis of ventilation safety theory, the simulation and prediction model is established. Then the computer as a tool to solve the actual mine ventilation problem. Taking Xingfu Coal Mine, which belongs to Fuxin Mining Group, as an example, based on the field measured data, the MIVENA system is used to carry out accurate simulation. The ventilation resistance of the original Sunjiawan system accounted for 21% of the total resistance, and the branch of the large wind resistance in the ventilation system of Xingfu Coal Mine was calculated. The branch of the ventilation system is mainly located in the new auxiliary shaft, Yi-400 main exhaust air passage, and the second and third belt roadways, etc. Based on the calculation and analysis of ventilation network, a tracer gas experiment was carried out on some roadways of Xingfu Coal Mine, and a mathematical model of tracer gas concentration diffusion was established and simplified. The results of experiment and simulation were compared and analyzed. The key air leakage area of Xingfu coal mine is diagnosed. In view of the above three problems, the ventilation system of Xingfu Coal Mine was optimized and reformed from the aspects of reducing resistance regulation, sealing air leakage and simplifying the production system of Sunjiawan. The optimized ventilation system was calculated by MIVENA system. The ventilation system of Xingfu coal mine increases about 10 percent of the total air volume and reduces the air pressure by about 25 percent, which increases the economic benefit of the mine.
