Soil response is an important parameter that affects plant health and its resulting quality. It also affects the intake of chemical substances. These include not only nutrients but also e.g. heavy metals. It is well known that soil fertilization using organic matter, preferably manure, positively affects soil reaction. Manure can be enriched with various substances in order to increase its efficiency. However, this may mitigate the positive effects of manure on the soil or it may have a negative impact on soil pro...

The transport sector is one the most energy-intensive sector on planet. Whether we are discussing about cargo or travelers, the transport sector is causing environmental damage. Therefore an Impact Assessment study in the Transport sector concerning energy efficiency should draws attention. First of all the transport cost decrease, and second it contributes to the natural resources to be saved by the fossil fuels.Reducing greenhouse gas emissions and current rate of global warming can happen using a proper energy ...

The studies of the rock mass movements on considerable depths can be carried out based on the network of geodetic points, present in the mining excavations. Such a network is very unfavourable in a sense of geometry, because it is, in a large part, built of open traverses. Often the only way to raise the accuracy parameters of such a network is making the azimuth measurements on selected sides of the network with the use of gyrotheodolites. Applying the carried out gyroscopic observations in the levelling of the n...

One of the most important issues in the problem of fusing partial maps without common reference frames into one large global map is requirement of manually obtaining the locations of mobile 3D laser scanners that are used to scan the environment. In this paper, we propose a novel positioning approach to obtain the locations of 3D laser scanners. The main limitation of our approach is that 3D laser scanners must be equipped with long-range wireless interfaces or off-the-shelf long-range wireless interfaces must be ...

The copper ore deposit in Poland is extracted by three underground mines which belong to KGHM Polish Copper JSC. Since the very beginning, copper ore mining has been accompanied by seismic activity and rock-burst hazard controlled by means of several prevention activities aiming at assessing and combating the danger. Seismology is the prime method to measure seismic activity i.e. the number and energy of rock mass shocks. The hazard monitoring also encompasses measurements of the convergence of mine workings, i.e....

The construction of a residence involves a comprehensive transposition of ideas into a well-designed project with numerous details, views, pictures, sections, material lists, hence leading to low implementation costs, with no mistakes, and with good ergonomics. However, the urbanistic constraints must be considered when designing a house, i.e.: the land minimum width on the street; the minimum area for which the building permit can be obtained; the minimum size of the construction to be built in relation to the la...

The role-oriented concept of programming is becoming more common in recent times. Expanding the traditional object-oriented paradigm, it allows us to apply a more flexible approach to the development of the information system and simplify the task of the developer. The use of role-oriented structures in modern applications raises the question of storing them in a database. The task of extracting homogeneous semantic entities from structured documents has a high potential for solving with the use of roles or their ...

Mining exploitation in an underground mine is the main factor disturbing the balance within the rock mass. By removing the obtained raw material from the rock mass mining activity leads to changes in the broadly understood state of the natural environment. Extraction of the raw material ? hard coal with barren rocks is often associated with the need to undertake dewatering of the rock mass and discharging mine gases into the atmosphere. The process of extracting the raw material from the deposit and the accompanyi...
