摘  要

陽泉煤業(yè)集團有限責(zé)任公司新景礦（以下簡稱新景礦）是由原陽泉三礦的一期改擴建新增井田部分（西部區(qū)）與三礦豎井重新組建的礦井。

佛洼分區(qū)位于新景礦的西南部，東部以y=86600與蘆湖南、蘆湖北分區(qū)為界，西部以y=82000與規(guī)劃中的七里河井田為界，北部以x=103000與新景礦北條帶為界，西南部為保安煤礦，南部隔桃河為陽煤集團二礦，分區(qū)東西長4600m，南北寬平均3200m，面積為14.76km2。主要可采煤層有3號、8號、15號煤。我設(shè)計佛洼南條帶15號煤，煤層傾角小，小于12°，該煤層?xùn)|部、北部厚度大.煤層平均厚度為5.73米。該分區(qū)東部與蘆湖南、蘆湖北分區(qū)相鄰，靠東部約一半?yún)^(qū)域地質(zhì)勘探程度較高、構(gòu)造相對簡單；靠西部約一半?yún)^(qū)域勘探程度較低，大部分為C級儲量。 

目前佛洼分區(qū)正處于開拓階段，由于15號煤煤層較深，平均深度在+350水平，我計劃采用雙立井開采，開采軌道大巷、運輸大巷、回風(fēng)大巷均在+350水平布置，由于煤層傾角小，構(gòu)造穩(wěn)定，采用帶區(qū)開采掘進減少，分為四個條帶。經(jīng)計算三量一個工作面和一個掘進面就滿足生產(chǎn)要求，工作面長度為200米，傾斜長度為2200米，工作面采用綜合機械化放頂煤開采，采用三班開采一班檢修，一班割兩刀煤放一次頂，作為一次循環(huán)。

佛洼分區(qū)設(shè)計生產(chǎn)能力為1.2Mt/a。采用一次設(shè)計、一次建成投產(chǎn)的移交方式。

設(shè)計在井田中部佛洼新建一進回風(fēng)立井。進風(fēng)立井裝備梯子間、排水管、壓風(fēng)管、消防灑水管以及動力電纜等，為進風(fēng)井兼安全出口；回風(fēng)立井為專用回風(fēng)井。形成佛洼風(fēng)井除提升之外相對獨立的供電、通風(fēng)、排水、壓風(fēng)等系統(tǒng)。

井下主運輸采用膠帶輸送機，可實現(xiàn)從佛洼分區(qū)到蘆湖南分區(qū)直至地面膠帶輸送機一條龍連續(xù)運輸，用人少、效率高、故障率低、安全性好，有利于實現(xiàn)集中自動化控制與管理。輔助運輸采用無極繩連續(xù)牽引絞車牽引1.0t系列礦車運輸，可以保證本區(qū)輔助運輸?shù)倪B續(xù)性。主輔運輸?shù)倪B續(xù)性為新景礦的高產(chǎn)高效提供了有利條件。

礦井采用中央并列式通風(fēng)，由于該礦為高瓦斯礦井，全礦井瓦斯絕對涌出量為44.4 m3/min，光靠通風(fēng)滿足不了通風(fēng)要求，需要提前進行瓦斯抽放，采用外錯尾巷和傾向高抽巷進行提前抽放。

佛洼風(fēng)井工業(yè)場地總平面布置，充分結(jié)合地形的特點，因地制宜地布置在三個臺階上，場地布置緊湊而合理，場地運輸環(huán)節(jié)簡單，土方工程量較少。

本礦井煤層瓦斯含量高、生產(chǎn)能力大，生產(chǎn)中應(yīng)加強通風(fēng)系統(tǒng)和瓦斯抽放系統(tǒng)的管理、檢測和調(diào)整工作，以保證礦井安全生產(chǎn)。

Abstract

     Yangquan Coal Industry Group Co., Ltd. The new King Mine (hereinafter referred to as the new King Mine) is a former three-Yangquan mine add an expansion Waida part (west) and three mine shafts of the mine re-established. 

Buddhist wa ore district is located in the south-west of the new King, in the eastern part of y = 86600 and Lu Hunan, Hubei Lu district is bounded to the west and y = 82000 Qilihe planned for the mine sector, in the northern part of the new x = 103000 King Mine strip bounded by the north, the south-west coal mine for the security, every other southern Taohe Yangquan Coal Industry Group for the second mine, area from east to west 4600m, the average North-South width 3200m, an area of 14.76km2. Main coal seam 3, 8, 15, of coal. I designed the Buddha depression on the 15th strip south of coal, coal seam dip small, less than 12 °, the eastern part of the coal seam, the thickness of the northern Great. Seam thickness of 5.73 meters on average. And Lu in the eastern district of Hunan, Hubei Lu adjacent district, on the eastern half of the regional geological survey of about a higher degree of relatively simple structure; on about half of the western region with less exploration, most of C-class reserves. 

At present, the Buddha is in the district to develop depression stage, 

on the 15th as a result of the deeper coal seams, with an average depth in the +350 level, I plan to dual-shaft mining, the exploitation of the track roadway, transportation roadway, roadway back to the wind in the level of +350 layout, as the seam angle small, structural stability of the exploitation of driving with a reduction in area, divided into four bands. By calculating the volume of a three-face and a driving surface on the production requirements to meet, face length of 150 meters, tilt length of 2200 meters, take the entire face using a high-level caving mining, the exploitation of a group of three maintenance intervals two cycle twice a top coal caving. 

Dover district sunken design production capacity of 1.2Mt / a.

The design of the Buddha in the central depression Waida a new shaft into the return air. Equipped with a ladder into the air shaft, the drainage pipes, duct pressure, fire sprinkler pipe and power cables for safety into the ventilation shaft and exports; return air shaft ventilation shaft for the dedicated back. Buddha depression formed in addition to upgrade the ventilation shaft outside the relatively independent power supply, ventilation, drainage, wind and other pressure systems. 

The use of underground main transport belt conveyor can be realized from the Dover district sunken into the ground until Lo Hunan district one-stop conveyor belt for transport, use less, high efficiency, low f

ailure rate, safety, and is conducive to centralized automatic control and management. Auxiliary transport used for traction winch rope wuji 1.0t Series tramcar traction transport, supporting in this area can guarantee the continuity of transportation. The continuity of primary and secondary transport ore for the new King of the high yield and efficiency have provided favorable conditions. 

Central parallel mine ventilation, mine is due to high gas mine, all mine into an absolute gas emission for the 44.4 m3/min, ventilation alone can not meet the requirements of ventilation, exhaust gas needs in advance, using the outside lane and toward the end of Lane advanced to the high drainage pumping. 

Buddha air shaft depression general layout of industrial facilities, fully integrated feature of the terrain, according to local conditions in the three steps of layout, site layout and reasonably compact, space transportation simple, low earthworks. 

Coal mine gas of the high production capacity, and production should increase the ventilation system and gas drainage system management, detect and adjust its work to ensure that mine safety in production. 

Key words： first-wide adoption of high-level caving central ventilation shaft to open up side by side
