Description
II
Изобретение касаетс горной промышленности и может быть использовано дл изучени виезапиых выбросов горных пород в лабораторных услови х. .The invention relates to the mining industry and can be used to study Wiezepai rock emissions under laboratory conditions. .
Известеп способ моделировани внезапного выброса угл н газа, заключающийс в быстрой, разгрузке предварительно нагруженного блока угл {1j.A known method of simulating a sudden ejection of coal gas, which consists in the rapid, unloading of a preloaded block of coal {1j.
Однако при этом способе моделируетс на внезапный, выброс, а разрушение блока (конструкции) остаточными напр жени ми, возникающие при объемно сжатии, а так-же отсутствует геометрическое сходство модели и реального объекта (горна выработка , забой).However, this method is simulated for a sudden ejection, and the destruction of a block (structure) by residual stresses arising during volume compression, and there is no geometrical similarity between the model and the real object (mining, bottomhole).
Известен способ моделировани внезапного выброса горной породы, включающий отбор керна породы из массива, изготовлег ние него образца, размещение последнего в камере высокого давлени , имитацию -забо горной выработки в одном из торцов образца, нагнетание, газа в другой из торцов образца, нагрузку последнего и регистрацию процессов, происходимых в образце , посредством измерительной аппаратуры (2).There is a known method for simulating a sudden ejection of a rock, including sampling rock cores from an array, making a sample of it, placing the latter in a high pressure chamber, imitating for mining at one of the ends of the sample, forcing, gas at registration of the processes occurring in the sample by means of measuring equipment (2).
Однако этот способ не- позвол ет моделировать и изучать услови , возникаюн не в газоносном выбросоопасном пласте при ттроведен и горной выработки н при приближении забо выработки к выбросоопасной зоне.However, this method does not allow to simulate and study conditions that do not arise in a gas-bearing outburst layer at ttroved and mine workings when approaching the bottom hole to the outburst zone.
Целью;изобретени вл етс повышение точности моделировани выброса горной породы за счет созданн условпй моделирова- нн более близких к естестве.чным. ,The purpose of the invention is to improve the accuracy of modeling of rock outburst due to the created conditional simulations closer to natural ones. ,
Это достигаетс тем, что в торце образца , имитирующего забой горной выработки , создают посто нно движущийс забой путе.м высверливани , а нагрузку на образец создают нагнетанием жидкости п камеру. На чертеже представлено устройство дл This is achieved by the fact that at the end of the sample that simulates the bottom of a mine workout, they constantly create a bottom hole by drilling, and the load on the sample is created by injecting fluid into the chamber. The drawing shows the device for
5 моделировани внезапного выброса горной породы, разрез.5 simulations of a sudden outburst of rock, a slit.
Способ осуще€т.вл ют следующим образом .The method is implemented as follows.
В камеру высокого давлени помещают угольный образец 2, керн породы, ютобранный из массива. К торцу 3 образца 2 подвод т газ под давлением и в камере 1 с на.код щимс в ней образцом 2 создают УСЛОВИЯ объемного напр женного состо ни A coal sample 2, a core of rock, selected from an array, is placed in a high pressure chamber. The end face 3 of sample 2 is supplied with gas under pressure and in the chamber 1 with the code 2 in it, the CONDITIONS of volumetric stress state are created.
