rock reduction
解釋
巖石崩解-
The rock types comprise the delta front subfacies subaqueous distributary channel, channel - mouth bar and distal bar microfacies, and delta plain subfacies subaerial distributary channel microfacies sandstones and siltstones. as for the reservoir quality, the subaqueous ( subaerial ) distributary microfacies channel sandstones are the first, the channel - mouth bar microfacies sandstones come second, the distal bar microfacies sandstones is the third, and the last one is the interdistributary bay microfacies sandstones. the intense compaction, pressure solution and late carbonate cementation are responsible for the reduction of the porosity and permeability of the reservoir rocks
三角洲前緣水下分流河道、河口砂壩、遠砂壩及三角洲平原水上分流河道微相決定了儲集巖的發育，分佈及原始物性條件；水下（上）分流河道微相砂體厚度大、物性和孔隙結構好，次之為河口砂壩微相砂體，遠砂壩微相砂體儲集性較差，而分流伺灣微相砂體物性和孔隙結構最差。 -
According to roof safety factor of 1. 2 for the mined - out area, minimum safety roof thickness at different rock in various span mined - out area was calculated by flac software, which transfixion of plastic zone was taken as criteria of roof breakage by using strength reduction technology and dichotomy theory
摘要利用強度折減技術和二分法原理，以塑性區的貫通作為頂板破壞的標準，當采空區頂板的安全系數等於1 . 2時，利用flac軟體計算得出各種跨度空區在不同巖層中的最小安全頂板厚度。 -
Degeneration problems of karst soil fertility are mostly soil leanness, vegetation reduction, and natural environment erosion and rock desert

Large pieces of rock are only suitable for use as road surfaces in the form of fine gravel, run - of - mine coal needs to undergo a size reduction prior to further treatment, and lumps of ore need to be crushed to small pieces because sintering plants require feed material with a high degree of fineness
公司的目標是生產破碎機和洗礦機。只有砂礫狀的巖塊才適合於路面，原煤必須首先要被擊碎才能被加以利用，礦石必須被搗碎，這是因為燒結設備只能處理細微物料。 -
Furthermore tunnel structure commonly is designed by analogy method. on design, often, normally in view of safe consideration, adopt the method that reduction surrounds rock classification and uses fussy construction technology. so as soon as coming, engineering investment is certainly increased and construction project time is prolonged
且隧道結構一般按類比法設計，出於安全考慮，設計上一般採用降低圍巖類別，使用復雜的施工工藝來提高施工的安全性，這樣無形中增加了工程投資費用且延長了施工工期。 -
During the deep - hole blasting for the excavation of guishan quarry for construction of baoquan pumped storage hydropower station, the blasting powder factor and the charging concentration of the blasting powder in the rock are reasonably controlled, and then the rate of blasting chunk is greatly decreased with the reduction of the working amount of the boulder blasting afterwards in conjunction with the suitable excavator and crusher etc
摘要在寶泉抽水蓄能電站工程龜山料場開挖的深孔爆破中，合理控制了爆破單位耗藥量和炸藥在巖石中的集中度，最大限度地降低了大塊率，並結合使用適宜的開挖及破碎機械等措施，從而減少了二次爆破工作量。 -
6 ) according to character of zone which shen - dong diggings locates, put forward main measures of environment protection and zoology build in shen - dong diggings and surround it, full analysis water resource carrying capacity, study cleaning mining technique from reduction waste rock, fathering powder dust and deal exhaust gas pollution aspects, found environment ensuring system of sustainable development of shen - dong diggings
6 ）根據神東礦區所處地域的特點，提出了神東礦區及其周邊地區環境保護與生態建設的主要措施，對礦區水資源承載能力進行了全面分析，從減少井下出肝量、井下粉塵治理、井下廢氣污染治理等方面研究了礦山潔凈開采技術，建立了神東礦區可持續發展的環境保障體系。 -
This paper, based on collecting many empirical determinations of strength parameter for jointed rock masses all over the world, puts forward the improved empirical determination of strength parameters, that is to say, " size effect reduction factor " and " jointed rock reduction factor " of the intact rock specimen for the study on jointed rock mass strength parameter, and applies to the a typical location of the dam, which proves that this methodology is feasible and rational, and a new way for study of strength parameter in jointed rock masses is established
在大量收集國內外節理巖體強度參數經驗確定方法的基礎之上，提出了改進的節理巖體強度參數經驗的確定方法，即對完整巖石進行「尺寸效應折減」與「節理化折減」的二次折減法，並應用於某壩址區工程實例中，所得的計算值與現場實測抗壓強度值接近，較以往的經驗確定方法更加準確，證明了節理巖體強度的降低是尺寸效應與節理化綜合作用的結果，為節理巖體強度參數的研究提供了一條新的思路。 -
